Syn cookies are not relevant here - syn cookies prevent your TCP state
table from filling up with SYN_RECV connections. As long as your
sequence numbers are sane, even without syn cookies nobody can fake a
3-way handshake.

Hi,
I have a qmail setup where all my mail boxes are stored on a NAS (EMC
filer). Qmail is running on linux. Someone kindly suggest be a backup tool
which can backup open files i.e, opened by qmail (for ex: when a user opens
his mailbox for reading mails...). Also, does qmail open files in exclusive
mode or shared mode?
Thanks
Sunil

With regard to collissions: when updating the timestamp everytime,
chance increases that shortly after the process exits, it's PID is the
next PID assigned since the global PID counter has wrapped around, and
a delivery attempts to happen from the same PID in the same second.
Ofcourse, collissions are not a problem when maildir software conforms
to the rest of the spec.
The other issue is that when you keep the same timestamp for the
complete lifetime of the process, all messages with a different
deliverycount but delivered by the same process can still be grouped
together, should anybody find a need for that.
If you ask me, just update the timestamp everytime if that helps your
sorting. It won't likely cause collissions, and if you get a
collission, make sure you handle it gracefully and compliant.

Hi,
I am running qmail on solaris machine. It is currently looging all smtp

Sounds more like your passwd field format has changed... Did you change for
to MD5 passwds or the shadow passwd suite... Maybe its just time to look at
those tripwire reports.
Don't you hate how people show up on a list with boring installation
questions, which every experienced person probably wouldn't care about
since they've already installed the program successfully?
I know it tires me, which is why I'll be all the more appreciative if
someone here can help me with my boring installation question :-)
I installed qmail, and it works fine. I tried setting up the POP
server, and it's acting funny. When I connect it says "this user has
no $HOME/Maildir", which is false, since the user most definitely has
a Maildir. I start the POP server like this:
tcpserver -H -R -c100 0 pop-3 /var/qmail/bin/qmail-popup \
/bin/checkvpw /var/qmail/bin/qmail-pop3d './Maildir' &
I tried changing './Maildir' to '/home/ianb/Maildir' (the user I'm
connecting as), and it works! I started playing with strace and
putting little bits of code into qmail-pop3d.c and checkpassword.c to
figure out what's going on.
It turns out that qmail-pop3d is being run with uid 0 (root), so it's
trying to change to /root/Maildir (which doesn't exist) -- this is
what I've found through strace (getuid() == 0, $HOME=="/root"). I've
tried it with checkpassword, checkvpw, and checklocalpwd, and they all
have the same behavior. I see that these programs are supposed to
change to the uid of the user that is logging in.
Well, now I'm pretty darned confused. This is on Linux RedHat, mostly
with 6.0 components installed, glibc 2.1.1-6, qmail 1.03 installed
from source.
Ideas would be most appreciated. Thanks.

There's lots of reasons for it to fail; the Maildir isn't owned by the
user, has incorrect permissions on the path leading to it, is named
incorrectly, etc.

This shouldn't matter. Your checkpassword replacement is supposed to
set up $HOME, $USER, etc properly.

The same thing here works just fine using vmailmgr. Perhaps your
vmailmgr installation (in particular, checkvpw) is broken or
misconfigured.

That's what I've seen in the mailing list archives, but doesn't seem
to be the problem here. Like I said, when I replaced the startup
command with the full path of an actual Maildir (/home/ianb/Maildir),
it was able to change into this directory and download the mail
successfully. When I traced the program, it was trying to look in
/root/Maildir (though it wasn't downloading root's mail).

Exactly, but it doesn't seem to be doing so. Like I said,
checkpassword, checkvpw, and checklocalpwd all give the same results.
I don't know where to look next for the problem.
When I do a trace, I can't see what's going on inside these programs.
It gives a trace of qmail-popup and qmail-pop3d, but there's no
feedback from checkpassword. I haven't used strace before now, so
I might not be using it correctly.
Thanks,
Ian

You have to supply the option to trace all children (-f, or -ff). It
would be interesting to see your results.

Hi,
I'm using a spampatch write by Rask Ingemann Lambertsen, Marc Pohl,
Mark Delany and Erwin Hoffmann. I have problem whith SPAM, and I hacked
Qmail Code for solve this problem because in 2 cases after Client blocked by
this 2 lines, if I put "data" command connection is passed and SPAM is
granted.
Example:
telnet some.smtp 25
220 some.smtp ESMTP
mail from:<[EMAIL PROTECTED]>
250 ok
rcpt to:<some@domain>
553 sorry, your envelope sender is in my badmailfrom list (#5.7.1)
data
go ahead <- SPAM granted
In normal email clients (Outlook, Messenger, Eudora, etc) this feature not
work, but another's e-mail client's that (like telnet) not work whith result
code (error 553) this role is used for SPAMERS.
I've changed this lines:
Line 57 of qmail-smtp.c after patch:
out("553 sorry, your envelope sender is in my badmailfrom list (#5.7.1)\r\n"); }
by:
out("553 sorry, your envelope sender is in my badmailfrom list (#5.7.1)\r\n");
_exit(1); }
And this:
Line 61 of qmail-smtp.c after patch:
out("553 sorry, your envelope receipient is in my badreceipients list (#5.7.1)\r\n"); }
by:
out("553 sorry, your envelope receipient is in my badreceipients list (#5.7.1)\r\n");
_exit(1);}
I recompile qmail, and result is perfectly:
telnet some.smtp 25
220 some.smtp ESMTP
mail from:<[EMAIL PROTECTED]>
250 ok
rcpt to:<some@domain>
Connection closed by foreign host. <- SPAM is denied :�)
No more.

Your qmail-pop3d is broken. A pristine qmail-pop3d absolutely does not
behave this way:
[foo@twoflower control]$ telnet 0 25
Trying 0.0.0.0...
Connected to 0.
Escape character is '^]'.
220 discworld.dyndns.org ESMTP
HELO foo
250 discworld.dyndns.org
MAIL FROM: <[EMAIL PROTECTED]>
250 ok
RCPT TO: <[EMAIL PROTECTED]>
553 sorry, your envelope sender is in my badmailfrom list (#5.7.1)
DATA
503 RCPT first (#5.5.1)
Remove any patches you've applied to qmail-pop3d and
recompile/re-install. The problem will go away.

Indeed, I was thinking about the next message from the list, with pop3d
problems :). Thanks for the correction.

I have just checked with the spamcontrol 1.4.2 patch from
http://www.fehcom.de/qmail/qmail_en.html
and I can't see the problem mentioned by the original poster, so I think
he spoiled the patch(es).
The only modification at this place (badmailfrom) is that err_bmf()
takes two arguments for logging reasons.
This note is mostly for people that have applied this patch to prevent
them from panicing ;-)
Anyhow ... your suggestion is of course correct.

A few of us living in or around Amsterdam have organised an informal get
together on 12th September. The idea is to meet up, have a few drinks
together, and basically get to know in person the people that you might
have been emailing, but never met. We plan to meet at Leidseplein, near the
H�agen Dazs ice cream place, at 9pm.
If you're interested in joining us, please let me know, so I can give
you a couple of phone numbers, in case you can't find us or something.

Hi all,
I'm going to be writing a series of scripts to pass information from Qmail's
logfiles to RRDTool to graph. However, I need to know how best parse the logfiles in
Perl -- so, if anyone could point me in the right direction, I'd really appreciate it.
If and when this is done, I'll pass the scripts onto the list.
Thanks!

Hi
I'm using Qmail w/ vpopmail (latest stable version)
i compiled vpopmail with mysql option
i assumed that this vpopmail option allow you to store some of information
into mysql then files, apparantly i assumed wrong 'cause it stores in
mysql
and in files.. which is fine.. but! now i desided to move one domain from
one machine to another, i moved files and i moves data from mysql, now
when
using qmailadmin i'm trying to logon on domain it authorizate me but if i
click on any options like pop accounts i get this error
Error: could not change to directory
not to mention i get this in logs
vpopmail[31063]: vchkpw: No user found [EMAIL PROTECTED]:xxx.xx.xxx.xx
every time user trying to retrive his/her email
what else i missed? how do i fix it? and what's the proper way to move
domains from one vpopmail to another?
I used FreeBSD with Qmail with delivery option Mailbox, dot forward
and procmail.
What program is suitable so that my server can be poped (with pop3
protocol) including the mail that is in Mailbox and other folders ?
Thank You very much

Hi
I installed qmail+ldap on my system and it is working OK, now I need to
have all the control in the LDAP too but the available patch for the
control is for older version of qmail+ldap and I need to have this patch
badly because I am installing qmail on five machines with the same
config. in a cluster.
I need also to have user login in to my pop3/imap servers with their
complete mail address like user@domain to exapnd the namespace since I
am going to offer virtual hosting for mail, can it be done with qmail-ldap.
TIA

I haven't heard of Turbo (who's written the patch) for a long time. Last one
was he lost his job. It's a pity, he's a very nice and competent person. I'm
really missing the endless email discussions we had about qmail-ldap
modifications, patches, programming style and so on.
I don't use this patch and I don't think it is such a good idea - but this
depends on your usage scenario. For now, use the control files and rsync.

This is merely the qmail-ldap #1 FAQ, even before the qmail #1 (slow
smtp/pop). Use the qmail-ldap list archives for long discussions why this is
a bad idea and how to make uid's unique anyhow. The archives addresses are
in http://www.lifewithqmail.org/ldap/
