I had similar problems at one point. Turned out to be an error buried in
the script executed by qmail-qfilter. It only produced the error when it
hit a certain point in the script that only ran against messages coming
from a particular host.
I found my problem by putting the problem message in a text file and piping
it into my filtering program (like your log_sent). I immedately saw the
script error on screen and was able to correct it. You may need to monkey
with some environment variables to duplicate the problem environment,
though.

$RFC822.eml
I have made the qmail-filterq script (the one that immediately calls the
qmail-qfilter) so it doesn't actually pass onto anything (there isn't a
log_sent) and it still gives that error as of yet I havn't found where
there is a softlimit installed either as mentioned in a previous couple
replies
Any other suggestions?

Softlimit is part of the daemontools package.

You still haven't told us what your permissions are on the system on
which it is failing. Or does it only fail for certain clients? What
are the exact contents of your tcpcontrol rules file?

permissions are 755, only certain clients,
168.100.206.150:allow,RELAYCLIENT="",QMAILQUEUE="/usr/local/bin/qmail-filterq"
and i have the pasted the contents of the qmail-filterq file already too
the loggin works on some hosts that connect up via serialmail to relay its
only some hosts that it has issues on - (the softmail thing does sound
promising ---)

For some added confusion I put the softlimit command in after the
supervise and it didn't help
it DEFINATELY looks to be some type of limit thing though

I took a look at it any it seems pretty nice. However around here we
still use reflectors on the main mailservers and having a check for
the recipient's address in the recipient headers is needed. I don't
know if enough other people need that check to make it worthwhile doing.

I don't understand. What do you mean by a reflector? Why are checks on
the recipient's address in the headers necessary?

Thanks for this update! :)
one question, and one suggestion :
- is it possible / planned to use this autoresponder with vmailmgr accounts ?
(so with a v[add|del]autoresponder, or vchattr)
- suggestion : I really miss this feature from vacation in your autoresponder:
If the string $SUBJECT appears in the .vacation.msg file,
it is replaced with the subject of the original message
when the reply is sent.
Maybe you want to take it on your todolist ? :)
Regards,
Olivier

Reflectors are something sendmail has. You can have system wide aliases
that just deliver the message to more addresses. The alias can actually
point to file. For these kinds of messages, the tests you are using
won't see the mail as list mail.
If you don't mind not responding to bcc'd messages, checking for the
recipient's address(es) in the headers is a very good way to detect
mass mailings.
Making this kind of test does add some complications. You need to have
a list of addresses for the current recipient. You have to worry about
equivalent addresses that are too numerous to list manually (typically
this would be case insignificance and extension addresses).

Yes. The CGI support is already done (version 0.96.7), and
qmail-autoresponder comes with a script, vautoresponder, that can be
used to do this.

Sounds reasonable. I had been thinking of some way of putting the
original subject into the response. The other way I was thinking of
doing it would be a command-line option to add the original subject to
the reply with a given prefix.

So, in other words, a hard-coded mailing list, akin to having a .qmail
file containing:
&address1
&address2
&address3
...

But doing that requires doing a full RFC822 compatible parse of all of
the dozen headers that might contain an address. I've written such a
parser, and I'm not including it for this.

I consider it to be an absolute requirement for any autoresponder to not
reply to a message that isn't addressed to the recipient it is acting on
behalf of. Anything else is just begging for the sort of exponential
autoresponder meltdown that's happened on some mailing lists in the past
(most notably faq-maintainers).

Yup. Very annoying, but necessary. Otherwise, you'll end up sending
autoreplies to mailing list traffic, which is an absolute no-no even if
the mailing list isn't "properly" tagging messages with a Precedence
header.

Currently we are using qmail with regular Unix system accounts (with
Maildir boxes), but I'd like not to.
The main reason we use this is because we also use a radius server
(Cistron-Radius) and it authenticates though system accounts.
But ideally I'd like all the accounts to be in an single LDAP directory so
I can keep all accounts in a central location and not have to replicate
information. Also, I'd like the accounts to be maintainable by non-unix
users (either via web interface or Windows). A SQL backend would be nice
too. Also, I'd like SAMBA and SQUID to be able to authenticate through
the same database. I want everything. But I'm not sure about the best
combination of tools.
Any suggestions?

Here, I'm using qmail-ldap, and I have squid (using group_ldap_auth) and
apache (using auth_ldap) authenticating from the same database. and I'm
using web2ldap (www.web2ldap.de) to administer the directory through a web
interface. I modified the web2ldap files a little so that it has decent
descriptions of what fields are needed to control what in the ldap
directory as well.. it's all working quite well.. I'm not using SAMBA
though so I don't know if you can connect that with the ldap server, but
you may be able to through a ldap module for pam if it doesn't support it?

tcpserver must be run as root initially so that it can listen on port
25. So it's useless to give it `-u 0 -g 0'; it already is running as
those ids. You probably want to have it change to user qmaild and
group nofiles. See

Perhaps try something other than fetchmail, which doesn't even try to
do delivery by re-injecting with SMTP (that's just a recipe for bounced
mail).
You could try my own program, getmail. It's simple to use, and does local
deliveries directly into Maildirs (or mboxes, if you prefer).
It's very simple to set up, and determines local recipients based on the
contents of the Delivered-To: header as a first choice.
You can get it at http://www.qcc.sk.ca/~charlesc/software/getmail/

Have a bit of a strange situation here I'm hoping someone can help
me with. Up untill reciently, all the machines on our network had thier
own qmail server on them (set up by an admin who is no longer here) and
everything worked fine.
Now I'm trying to centralize to one smtp server on our gateway
with all the other machines having thier mail clients configured with our
gateway as thier smtp server.
I have the relaying up and running and the messages pass though,
but messages are bounced saying it couldn't find the host. This goes for
addresses within our subnet, the gateway/smtp server, and the outside
world. I've doubleckecked with nslookup, and we are getting name
resolution. A quick piece of maillog (gw=gateway/smtp/dns machine):
mydomain.net is our block of ips (sends to inside still fail)

Hmm, my guess is that in your tcprules you have RELAYCLIENT=" " or
similiar in the rule for the IP address of this connection. Did you
not notice in the logs that an extra character is being appended to
the end of your recipient's address? To allow relaying, set
RELAYCLIENT with an empty string, or else what's there gets appended
to the address.
That's my guess, anyway. Why don't you copy & paste the relevent
rule from your tcprules text file.

Last night we changed the hostname and main nameservers for our server.
Everything seemed fine till this a.m. we are now getting these errors:
"Jul 14 09:30:43 pisces vchkpw: vchkpw: Read error"
Any ideas on how to fix this?
Kathleen
Hi,
I want to use rblsmtpd-0.70 with tcp-server. can you tell me how I
make rblsmtpd-0.70 running with qmail ??
Rgds,
Al.
My company does a newsletter mailling of about 4 million. We are
trying to move things from sendmail to qmail. The hardware for the
qmail test is a compaq 2xP2,1gb,3 18gig scsi drives running redhat 6.2
with version 2.2.14 of the kernel.
Thursday morning we did a test mailing of 100,000 people. It's still
going alomst 24 hours later. According to other people's results, this
is terrible. As a first test we didn't change our scripts at all and
used the sendmail wrapper program. The scripts finished quickly but we
still have a ton of messages sitting in the queue.
My first step was to up the number in concurrencyremote to 100 and
restart qmail. However I still never got more than 16 or 17
qmail-remote's running at one time. I changed conf-spawn to 250 and
concurrencyremote to 240 but still the number of qmail-remote's never
got above 40. I then changed the concurrencylocal to 120 and the
timeoutremote to 60 but still no help.
My last step was to change the conf-split from 23 to 200. After that I
started getting syslog errors like:
Jul 14 09:48:31 charon qmail: 963582511.269118 warning: unable to stat
mess/14/476827
And nothing was going faster so I changed it back. I also have
sigalrm-ed qmail-send hoping to get the queue moving faster but that
didn't seem to help.
Here's part of the output from qmail-showctl:
qmail home directory: /var/qmail.
user-ext delimiter: -.
paternalism (in decimal): 2.
silent concurrency limit: 125.
subdirectory split: 23.
user ids: 502, 503, 504, 0, 505, 506, 507, 508.
group ids: 501, 502.
concurrencylocal: Local concurrency is 120.
concurrencyremote: Remote concurrency is 123.
databytes: (Default.) SMTP DATA limit is 0 bytes.
qmqpservers: (Default.) No QMQP servers.
queuelifetime: (Default.) Message lifetime in the queue is 604800
seconds.
smtproutes: (Default.) No artificial SMTP routes.
timeoutconnect: (Default.) SMTP client connection timeout is 60 seconds.
timeoutremote: SMTP client data timeout is 60 seconds.
timeoutsmtpd: (Default.) SMTP server data timeout is 1200 seconds.
So I guess my question is "What's going on???" :-) It seems that other
people have had this problem but the answer has always been "restart
qmail" which I did... We still have some messages in the queue to be
preprocessed if that matters.
My other question would be how to determine what the queue subdir
split should be.
Any help would be greatly appreciated.
Thanks,
Paul

I'm not an expert on the internals of qmail, but I see one problem...

When you change conf-split, you can't expect the new binaries to be able to
use the queue from the old binaries. It changes the assumptions that qmail
uses about which subdirectories particular files in the queue will be in.
The general method to change conf-split on a running machine is something
like the following:
-change conf-split
-compile qmail and install to a DIFFERENT location than the original.
Let it run in parallel with the old version (different queue, different
control directory, etc).
-wait until the queue of the original qmail instance is empty.
-compile qmail again with the larger conf-split, installing to the directory
of the ORIGINAL qmail installation.
-let the queue of the 2nd/alternate installation empty
-delete the 2nd/alternate qmail instance.

This can be changed in the source, I believe -- but it can depend on your
OS.

What is your hardware? What does `mailq` show (it'll be big)? Are most of
the messages remaining in the queue just bounces and deferrals?
If it's not just bounces and deferrals, you're hitting a bottleneck somewhere.
Unfortunately, you've given us no information to help determine what that
bottleneck is (network bandwidth, disk bandwidth, linear search time,
CPU, logging).
What are you using for logging, anyway? If its syslog, that could be your
problem right there.

well, now we upgraded to vpopmail-4.x.x, installed it with the same options
as before.
this time. instead of a read error, or the correct way of authenticating.
it appened MY ipaddress to the username.
so isntead of the logs showing
[[EMAIL PROTECTED]]
it would show
[username@:63.72.96.166]
Help, it's oen thing after another today :(

OKOK, i finally
read the "life with qmail" article as recomended...
i installed the
qmail system from scratch
it works now with
the qmail-pop3d and the qmail using maildir ...
now, to my
questions:
i have 3 MX records
pointing to this machine:
domain1.com,
domain2.com and domain3.com
i have a dns entry
for every domain as mail.domain1.com pointing to this machine also - lets call
it mailer.domain4.com
i just have to use
the virtualdomains with domain1.com:dom1 and
domain2.com:dom2
and then the users
of the pop will be dom1-sales and dom2-sales
i hope that up to
here im right
now, i dont want to
have /home/dom1-sales/Mailbox and /home/dom2-sales/Mailbox
but instead have
/mailuser/dom1-sales/Mailbox and
/mailuser/dom2-sales/Mailbox
is this possible
and if so, how?
also, i inserted
the command for pop3 as described in life with qmail into the
inetd.conf
when i test is as
instructed on the machine itself it works great
but when i telnet
to 110 from another machine, the authentication always doesnt accept the
password...
HELP
and thanks again
for pointing out that article, it helped make sense of all this new things and
concepts...

You can make entries for these addresses in /var/qmail/users/assign,
and let the homedir field be /mailuser/dom1-sales, etc. Or if these
addresses have system accounts (which doesn't necessarily sound like
the best way to do it, but it seems that's what you're doing), then
you can let /mailuser/dom1-sales be the actual home directory for the
dom1-sales user. (How to change an account's home directory depends
on the kind of system you have; check your system documentation, we
won't necessarily be able to help you.)

What exactly did you do to test it? What exactly are you doing when
it fails?

qmail-analog does this, among many other things. It's written by the
author of qmail, and is available from his website at http://cr.yp.to/

Uh, yeah, somethin like dat....

I've been given the task of setting up our own "blaster" for sending out
emails of our financial news and charts to our subscribers. We outsource
this right now, and it's abysmally expensive. Basically, we want 3 boxes
(or so) that run in parallel and blast out the emails, about 50 million per
month, but the subscription rate is growing rapidly each month. It needs to
handle bounced mail by dumping the addresses into a file for later retrieval
so they can be removed from the database, or by running an external script
for each bounced address.
I'm looking at getting 3 dell dual PIII 750's, with a 18 or 36GB 10000rpm
disk, and 512M or 1G of mem each. Each will run Linux or BSD.
Here's what I need to know:
1. How well does qmail take advantage of multiple processors? How much
memory and disk will I need? (we're at 50 million messages per month now,
and we only send out monday-friday, so that's over 2 million messages per
day, and it's only going up)
2. How many messages per day would one estimate that each of these servers
could do?
3. I read about mini-qmail and how it's about 100 times faster blasting out
email to QMQP servers. Since you can specify multiple QMQP servers, if I
have a fourth machine running mini-qmail and managing the actual mailing
list, can I add the other 3 as QMQP servers and have it load balance between
all 3 for sending out mail? (this way I could add more servers easily if I
needed to)
4. Can I easily make qmail run an external script for each bounced mail?
5. Anything else I should know?
Thanks.

Hey Jay,
I don't know much about setting that type of thing up in
qmail, but I would like to give you some ideas on the
hardware. I'm not sure how much load qmail would generate
in a scenario like that, but you may want to consider
Solaris x86 for the superior SMP performance. Also, you should
know what you're getting into on the Dell boxes if you choose
to run linux. I've got a Dell PE2400 dual that runs linux
and you're going to be at the mercy of Dell and Adaptec on
when you upgrade your kernel because they have some sorry
proprietary drivers for their RAID controllers that are
tailored to a specific kernel version and redhat sub-revision.
If you can put up with that, then Redhat Linux/Qmail on a
Dell runs very fast, I'm happy with mine. But at the same
time, I'm sitting on a kernel with a known suid exploit
hoping Dell will release newer drivers soon... It is much
nicer running Linux on an older Dell server of mine that has
an AMI MegaRaid card with drivers built into the kernel.

Indreectly, quite well as it forks many processes, thus if the OS takes
good advantage of your CPUs, then qmail inherits that advantage.
> memory and disk will I need? (we're at 50 million messages per month now,
Are these message unique per target address or the same. If unique, your
requirements are vastly different and very queue/disk intensive. If they
are the same and you take advantage or VERP support on qmail, then
your load will mainly be sending related which will benefit from
more memory, multiple instances, etc.

The qmqp support doesn't load balance. It simply takes the first one
it can connect to.

Absolutely.
> 5. Anything else I should know?
That all hinges on whether your emails are unique for each recipient or
not. Or more importantly, the average number of recipients per unique
email.
Regards.
I might as well jump into this since I just built a RAID 5 system for a
database.
The machine I built contains a DPT SmartRAID V SCSI RAID 0/1/5 controller
with 5 10000RPM 9.1 gig drives. The thing I notice about RAID 5 in the
right configuration is that you can throw tons of IO at it and you will
see little decrease in performance. Our Database server (Ya, I know, its
not MAIL SERVER) gets tons of IO and its nothing to it; just eats it up
and continues on its way.
I gotta say that you can't go wrong with this controller. It's a I2O
controller and thus supported in FreeBSD and Linux.
As Dave stated, you will get stuck with Dell and their proprietary
drivers, this I would avoid like the plague.

million messages per day, and it's only going up)
2. How many messages per day would one estimate that each of these
servers could do?
3. I read about mini-qmail and how it's about 100 times faster blasting
out email to QMQP servers. Since you can specify multiple QMQP
servers, if I have a fourth machine running mini-qmail and managing
the actual mailing list, can I add the other 3 as QMQP servers and
have it load balance between all 3 for sending out mail? (this way
I could add more servers easily if I needed to)
4. Can I easily make qmail run an external script for each bounced
mail?
5. Anything else I should know?
Thanks.

I already have Mandrake Linux 7.0 and 7.1 running on multiple Dell boxes
with no trouble, some of them took work to get going, but it runs well. I
have a few Crystal PC's here also that I may use instead, dual PIII 550's
with 512MB ram and 9 or 18GB 10000rpm drives. I'll probably use these for
testing.
The bulk of the messages will be the same content to many rcpt's. However,
once in awhile we'll have 100,000 different messages go out to 100,000
different people.
Since the QMQP support under mini-qmail doesn't load balance, can I feed it
a hostname with multiple dns entries (round-robin dns)? Or better yet, how
easy would it be to modify the qmail code to just load balance between them?

Are these message unique per target address or the same. If unique, your
requirements are vastly different and very queue/disk intensive. If they
are the same and you take advantage or VERP support on qmail, then
your load will mainly be sending related which will benefit from
more memory, multiple instances, etc.

The qmqp support doesn't load balance. It simply takes the first one
it can connect to.

Absolutely.

That all hinges on whether your emails are unique for each recipient or
not. Or more importantly, the average number of recipients per unique
email.

I agree with the earlier poster that more spindles for your queue
(c/- raid) is a good thing in general.

The manpage for qmail-qmqpc tells us that they have to be IP addresses
in qmqpservers so a RR DNS won't help. If all of the messages are generated
on one machine, then I'd be inclined to go for a much simpler solution
than modifying qmail. I'd have an instance of qmail for each outbound
server with the appropriate qmqpservers entry, then have your queue
insertion script do a round-robin itself by simply cycling thru
the qmail-inject command associated with each instance.
for instance in 1 2 3 4 5
do
getnext_message_details()
/var/qmail{$instance}/bin/qmail-inject currentmessage .... details
done
Or some such.
Alternatively, if you have money to burn, maybe a layer four switch
with load-balancing skills.

Where would I start in the code to modify the QMQP servers list so that it
would load balance between all of the servers in the list instead of just
using the first one it can contact? This would be very useful to me. I
assume qmail-qmqpc.c is one of them, are there others I would need to play
around with?

Line 153 of qmail-qmqpc.c is a good place to start. It's a trivial
loop that would benefit from something like adjusting the starting
point by some random value. Eg:
randj = rand() % servers.len;
i = 0;
for (j = randj;j < servers.len;++j)
if (!servers.s[j]) {
doit(servers.s + i);
i = j + 1;
}
Then repeat the loop from zero to randj - 1
i = 0;
for (j = 0;j < randj;++j)
...

Jay,
That's the beauty of having multiple instances, not having to patch qmail.
All you need to do is install qmail once per machine (ie, /var/qmail1,
/var/qmail2,...). Then have the script that does the mailing call randomly
on of the /var/qmail#/bin/qmail-inject. This will emulate round robin
without any patching.

Won't this way be a performance hit though? I admit, it is an easy solution
and would work excellent, but I have to think about efficiency also. C code
is much faster than shell or perl, and I'd like to set it up once and not
have to ever worry about again, or at least for a long, long time.
As I said, we're doing 50 million emails a month right now, but this is
increasing substantially each month, and as we rollout new subscription
services, we'll have even more load. Sending 10 times this amount by the
same time next year is a good possibility, possibly sooner as we seem to
underestimate the rate at which we're growing much of the time...

A massive mail injection, especially if the content is unique to the
user, can overwhelm a disk subsystem.
This is reccomending the exact -wrong- kind of disk system. RAID 5
has a write penalty, as it has to calculate parity for each write,
and write to multiple spindles.
The best type of RAID for small block writes is RAID 10 or RAID 1+0
(not to be confused with RAID 0+1). Even better is to use a disk
system with write-back cache. Ideally, you need at least seven
spindles.
I've seen great things with the Infortrend controller.
A great setup would be 1U pc's connected to an external RAID.

No. My experience is that the cost of running a script to inject the mail
in a way similar to that mentioned above, is pretty small compared to the
queue injection cost and the delivery cost. sh or perl will be fine.

You may also need to look at the scalability of the generation of the
emails. One system I recently looked at claimed to be able to generate
nicely unique emails at a targetted database, but it burned CPU like
it was free - just in generating the content.

Non-unique emails will most likely be generated by other machines and send
the box running mini-qmail via smtp. Non-unique emails will be a small
percentage of what gets sent out, for now.

Hi all,
I've got a small problem with autorespond. Here's my
situation. I have a vpopmail server, I'm using qmailadmin
and autorespond. I have a domain where I have a bunch of
users. As these users leave, I want anyone who emails their
old address to receive a canned response I've developed.
I figured autorespond would be good for this so I made a
new autorespond using [EMAIL PROTECTED] as the address.
So when the users leave, I delete their pop account and make
a forward in it's place that forwards from their old address
to [EMAIL PROTECTED] This does have the desired effect
of the original sender getting my canned response. The bad
part is that qmail detects it as a mail loop and also mails
the postmaster with this:
This message is looping: it already has my Delivered-To line. (#5.4.6)
I'm guessing that's because the message gets a Delivered-To line
when it comes in, but then it's redirected to another locally
delivered address before autorespond sends it back to the original
sender. Is there a way to avoid this or a better way to
accomplish what I'm trying to do?
Thanks in advance,
Dave
in /etc/aliases i added
autortest: alias-autor
then i created the file
/var/qmail/alias/.qmail-autor
it contains:
|/var/qmail/alias/autorespond 10000 100 /var/tmp/autor.txt
/var/tmp/autorespond/no-mailbox
(that is one line, no matter how your email client wrapped it here)
not sure if you really need that "100" there, but if tons of list users
try this now ...
/var/tmp/autor.txt contains this:
From: Mail Service Problem <[EMAIL PROTECTED]>
Subject: Recipient no longer exists (Auto-reply)
The recipient of your message below does no longer receive mail here.
--- Original Message ---
works fine if you email [EMAIL PROTECTED]
(try it soon cause i will remove that before it gets popular :)
this uses Eric Huss' autorespond by the way (thanks for that one, Eric)
hope this helps

When using vpopmail you must use the full email address like
[EMAIL PROTECTED] If using netscape it would be amarc%domain.com It's all
stated clearly in the documentation.

Do not meddle in the affairs of sysadmins, they are quick to anger and
have no need for subtlety.
It is true that qmail doesn't do anything with the inode->filename
mapping after it is made, besides have unique file names, and that
replacing that algorithm (which certainly succeeds in providing
insight into How The File System Works) with a different algorithm
that also guarantees uniqueness would break nothing?

yeah.
i'm not sure how few bits you guys want... but there's the code i put into
apache 1.3 for mod_unique_id which generates a 112-bit unique id subject
to a bunch of completely reasonable constraints. see
<http://www.apache.org/docs/mod/mod_unique_id.html> for documentation.
feel free to snarf the code under any license -- it's essentially
unchanged since when i put it in there.
it's basically a <timestamp, local_ip_address, pid, counter> tuple.
we replaced qmail's filename generation with this at cp -- mostly because
we're still living with solaris 2.6 and it doesn't cache filenames longer
than 31 characters; the shorter filenames helped a bunch.

The numbering scheme that Qmail uses when delivering mail to a Maildir, is there some
kind of method to the madness. Can I count on the numbers on the pieces of email to
increment every delivery? What do the numbers represent?
