Help wanted
Hi there, Let me introdce myself first. My name is Schajee and I'm a web developer. My company requires me to setup a complete Hotmail styled email service for use by its employees. I've been searching a solution to this problem and I found a lot of them but none matched my requirement, so I was forced to look for other solutions. I found qmail by accident and I kinda liked it. I've been using it for a some days now and I think it meets my requirments. So the question is how do you setup a mail service like Hotmail. I'm ready to develop a web based MUA which works with qmail and hopefull this should do the trick. So, anybody out there who has either worked on it before or has some experiance in working for such a thing... please let know so that we can sit down and talk about this.

Discarding mailer_daemon mail....
Is there any way to discard any Email the mailer daemon generates? Each day, the queue on our server builds up between 7000-1 Email in the queue that the mailer daemon's trying to return. (All spam, of course, the return address being bogus in some way) I have to run a script every night that deletes all DAEMON mail then restart the queuing system in order to not have the queue utterly overload. (much over 15000-2 in the queue and the system bogs down trying to sort out what Email it's trying to send) If I let the system sort this out on it's own, by the time the 4 day waiting period was up there'd be 45000 Email laying about the queue. Or maybe some way to limit the 4 day delivery time to maybe 18-24 hours. (This system is only for local delivery, it does no outgoing SMTP other than trying to return Email) Greg

Schagee, I've only just started playing with it, but squirrelmail has an awesome look and feel and seems to be extremly fast against courier-imapd. It runs under PHP4, is open-source, and ready to rock-and-roll. It took me all of about 2 minutes to install, configure, and run my first test. It loaded up my IMAP account (with over 80 folders and 30k messages) in less than 5 seconds. It's even faster on a more normal account.

pop3-problem with vmailmgr
Hello... Today I have setup a qmail-server with vmailmgr and omail for testing and hey it works very well - I will soon replace my sendmail-server :-) But I have a problem with the pop3-server. I can connect and the server accept my passwor, but I can't get any mails form it. I see always this message: this user has no $HOME Maildir. So vmailmgr save the mails in $HOME/users/username and not in $HOME/Maildir!? Must I patch the pop3-server? I found nothing about this problem! I read follow in the vmailmgr-howto: Configure qmail-popup/qmail-pop3d to use `checkvpw` as the password checker. This step is dependant on how you have installed qmail. Replace `checkpassword` in the command you use to invoke qmail-popup/qmail-pop3d (either in `/etc/inet.conf` or in a `tcpserver` command) with `checkvpw`. And/Or at the prompt type: `echo checkvpw /var/qmail/control/checkpassword` So my command-line of the pop3-server shows like this: tcpserver 0 110 /var/qmail/bin/qmail-popup servername /usr/local/bin/checkvpw /var/qmail/bin/qmail-pop3d But I doesn't work :-( Thanks Severin Olloz

qmail Multiple MX Problem
Hi all I have this problem delivering mail to certain hosts that have multiple MX entries. Other than that everything is working fine. Let me explain the scenario more. I have mail being sent to some user at server A and server B. Server A and B have 3 MX entries in their lookup. The first two entries in these are higher in preference but are unavailable to the net traffic (for some reason ). What i think is happening is that qmail is trying to connect to the first MX entry and for some reason the server sends SMTP serrvice not available to qmail at my end. So the mail is put in queue and then qmail retries the first server in MX entry. I have found a work-around in the sense that i entered smtproute individually for thse two servers A and B. It is working now, but i was wondering if anyone had more insight on why qmail was not looking up the other 3 mx records. Thanks in advance all, Saleem __ Do You Yahoo!?

Greg Moeller [EMAIL PROTECTED] wrote: Greg Moeller [EMAIL PROTECTED] wrote: Is there any way to discard any Email the mailer daemon generates? No easy, built-in way, but then again, you shouldn't need it. queue management in qmail is completely automatic. Your system is misconfigured. What split value are you using? What filesystem on what operating system? What kind of disk/array is the queue on? If your system bogs down because of the number of (basically inactive) messages in the queue, you've configured your system with values which are inappropriate for the load you're trying to serve. The system is dual processor Sparc 450, and an A1000 storage array. Qmail is running stock standard, as Dan intended. :) The queue was running on it's own bit of the array, multi spindle, mirrored. I've since moved it to /tmp, performance has gotten much nicer since then, almost a system crash will eat it. (see below for why I don't really care) Also, a large spam hit might eat the machine's RAM/swap(which I care about a bit more) (512 Meg of RAM, 256 of spool) The system delivers locally about 250,000 Email/day. You didn't explicitly answer my question about conf-split, but by stock standard, I'll assume it's the default of 23. This is probably too low for your system -- if you have five or ten thousand bounce messages sitting in the queue, you're getting lots of files in each directory. This is likely what causes your mail system to bog down when there's a bunch of bounce messages waiting in the queue. On a properly configured system, messages which are just sitting in the queue waiting for their next delivery attempt won't have much effect on qmail's performance. qmail's default queuelifetime is 7 days. You can lower it to whatever you want. However, reducing it too far will cause mail to bounce which would otherwise be delivered successfully. The only deliveries this server does is local, which I hope wouldn't take more than a few seconds, anything in the queue for remote delivery is a bounce. (which is why I don't care if the queue is lost, since all I lose is bounces) Once your system accepts a message from the internet, and issues a 2xx code in response to the DATA command of the SMTP conversation, you have agreed to do one of the following things: -deliver the message successfully to its final destination -return a bounce message to the envelope sender stating why delivery failed If you're discarding bounces, you're violating these conditions. That's unacceptable to many/most mail admins. Instead of trying to fix the symptoms (mail system bogs down when lots of inactive messages in the queue, most of which are bounces which have been deferred), why not fix the problem (inappropriate setup of MTA)?

Re: restart without rebooting
One problem with stopping a large Qmail system is waiting for everything to actually end cleanly. qmail-remotes can take some time to get done. At the moment, my system is: 992894705.645395 status: local 78/250 remote 110/250 Those remotes can take a very long time to time out. (10-20 minutes maybe) I tried automating a qmail stop/start sequence and even with killing all the remotes to help speed things up, I still couldn't get it stable. (occasionally the queue process would get confused and think there were still a few local or remote processes and there were none to be found, or if the queue were particularly chubby, just cleaning up after all the remotes were gone would take 2-3 minutes) This would cause the restart section of the script to fail because the qmail-start thought qmail was still going. (which of course it wasn't) Anyway, the moral of the story is on little systems it's not problem, on large ones it can be diceier. Greg

Re: qmail-remote (cry wolf?)
Hi,
[Summary: Some systems leave the fd_sets alone when select times out.]
I think it isn't relevant. qmail-remote doesn't seem to use select,
It does. timeoutread.c:
int timeoutread(t,fd,buf,len) int t; int fd; char *buf; int len;
{
fd_set rfds;
struct timeval tv;
tv.tv_sec = t;
tv.tv_usec = 0;
FD_ZERO(rfds);
FD_SET(fd,rfds);
if (select(fd + 1,rfds,(fd_set *) 0,(fd_set *) 0,tv) == -1) return -1;
if (FD_ISSET(fd,rfds)) return read(fd,buf,len);
errno = error_timeout;
return -1;
}
When select returns -1 (error case) everything is fine. When select
returns 0, i.e. in the timeout case, read is called if select has
not cleared the fd bit out of rfds. So if there really exist OS
which do not clear the bits, then qmail will potentially block in
read on those OS.
As to different OS behaviour, Solaris 2.6 (and 7) both say:
and errorfds arguments are not modified. If the timeout
interval expires without the specified condition being true
for any of the specified file descriptors, the objects
pointed to by the readfs, writefs, and errorfds arguments
have all bits set to 0.
On Solaris the above code would work without flaws.
whereas SunOS 4.1.4 (my usual 'old bsd system' benchmark) says:
descriptor sets. 0 indicates that the time limit referred
to by timeout expired. On failure, select() returns -1,
sets errno to indicate the error, and the descriptor sets
are not changed.
It doesn't tell explicitly what it does when it returns 0, but as
it's mentioned only in the error case, that the bits are not cleared,
one supposes that in timeout situations they are cleared, and thus
qmail will not have any problems.

Greg Moeller [EMAIL PROTECTED] wrote: You didn't explicitly answer my question about conf-split, but by stock standard, I'll assume it's the default of 23. This is probably too low for your system -- if you have five or ten thousand bounce messages sitting in the queue, you're getting lots of files in each directory. This is likely what causes your mail system to bog down when there's a bunch of bounce messages waiting in the queue. On a properly configured system, messages which are just sitting in the queue waiting for their next delivery attempt won't have much effect on qmail's performance. Hmmm, ok, what would a good split be for 7-10 in the queue? (about how many would build up over a weeks time before they started getting tossed anyway) It depends on a lot of factors, including hardware speed and filesystem efficiency. Solaris is particularly disgusting in this regard; on a high-end E4K with 15kRPM RAID, performance degrades unacceptably for an application of ours when there are as few as 200 files per directory. On low-end commodity PC hardware running on a Linux box with the ext2 filesystem, we get good performance with as many as 1000 files per directory. You said you're running on a Sun box. Try increasing conf-split so that your maximum expected queue load puts 200 files in each directory. For 10 messages, you'd need a conf-split of 500 or higher. Okay, that sounds too high to me, even. Let's try a limit of 1000 files per directory -- conf-split then has to be 100 or higher. The first prime after 100 is 101, so I'd try that. Anyway, yeah, I'd love to care for every one of these Emails, but for some reason I just can't. These wonderful folk have utterly wasted my server too many times by firing tens of thousands of Emails at the server within an hour or two and caused me to have to work for hours trying to clean up the mess. A bounce message that never gets delivered uses very little bandwidth. The only resource it's really using is some disk space and a few queue inodes. Can you spare those?

It doesn't tell explicitly what it does when it returns 0, but as it's mentioned only in the error case, that the bits are not cleared, one supposes that in timeout situations they are cleared, and thus qmail will not have any problems. Same with FreeBSD 4.3 - by implication. ... On return, select() replaces the given descriptor sets with subsets consisting of those descriptors that are ready for the requested operation. ...

Re: Qmail MIB?
If you use net-snmp (formerly known as ucd-snmp) it's fairly easy. Just configure snmpd to execute some external script, like any of the qmail-mrtg-* things (I use the qmail-mrtg-multilog package). Examples: snmpd.conf - rocommunity myreadonlycommunity your-ipaddress-here syscontact Whatever syslocation Some place exec .1.3.6.1.4.1.2021.50 qmail-mrtg /var/qmail/bin/qmail-snmpstat.sh qmail-snmpstat.sh #!/bin/sh /bin/cat /var/log/qmail/qmail-send/@* /var/log/qmail/qmail-send/current | /usr/local/bin/qmailmrtg -4 /usr/local/bin/qmail-mrtg-queue /bin/cat /var/log/qmail/qmail-send/@* /var/log/qmail/qmail-send/current | /usr/local/bin/qmailmrtg -3 /bin/cat /var/log/qmail/qmail-send/@* /var/log/qmail/qmail-send/current | /usr/local/bin/qmailmrtg -1 /bin/cat /var/log/qmail/qmail-send/@* /var/log/qmail/qmail-send/current | /usr/local/bin/qmailmrtg -2 This will put the printed output from the commands into a table under the 1.3.6.1.4.1.2021.50 OID. I use this to get stats into Cricket/RRDTool. It's a bit slow though, it takes some 5-10 seconds to process the logfiles.

Sounds like the permissions or location of the todo directory in the queue aren't correct. There's probably other problems with the queue as well. To fix this, you could blindly do the following: 1. stop qmail 2. cd to your qmail source directory (where you unpacked the .tar.gz file). 3. do `make setup check' Or, send another message to this list, including the unedited output of the `qmail-showctl` command, and the output of `ls -ld / /var /var/qmail /var/qmail/queue /var/qmail/queue/*` Charles -- --- Charles Cazabon[EMAIL PROTECTED] GPL'ed software available at: http://www.qcc.sk.ca/~charlesc/software/ Any opinions expressed are just that -- my opinions. ---

administrative copy of qmail mails
Dear Sir/Madam, I have read the Life With Qmail in the web. I have found it very interested and i have set up my mail server using Qmail and i found it is very great!! I have a problem here about Qmail, would you please kindly help me to find out the answer..?? I have set up my qmail server and it can run properly in the past month till now As some reasons, we decided to have make some configures.. I need to configure the qmail server which can automatically keep a copy of in and out mail of some specified address in some domains. For example, in the domain abc.com there are three email address: [EMAIL PROTECTED], [EMAIL PROTECTED] and [EMAIL PROTECTED]. And all email send from or to [EMAIL PROTECTED] will need to have another copy of the mail in the email box [EMAIL PROTECTED]. For incoming email, i think it can easily handled by ".qmail" files. However, for outgoing mail. How can i do so...?? Or is there any integrated method that i can do both in a simple manner. Hope you can answer me. Best Regards, Raymond Hui

I set conf-cc and conf-ld to 'gcc -g', edited timeoutread.c slightly
to save the return value of the select in a variable, then built
qmail-remote and put it in place of the live one. I'll attach a patch
matching what I did to timeoutread.c.
% Also, how to terminate the process so that I can 'fling' gdb at it?
I wasn't planning on terminating it. Rather I was thinking of using
gdb's attach command to take over the process, and then start
examining variables. Mostly, I was going to wing it.
I expect the full attachment sequence to look something like this:
(gdb) attach pid-of-stuck-qmail-remote
(gdb) symbol-file /var/qmail/bin/qmail-remote
(gdb) directory path-to-qmail-source-with-modified-timeoutread.c
(gdb) bt
(gdb) up -- repeat until at timeoutread() stack frame
(gdb) p res
(gdb) p fd
(gdb) p rfds -- or something like that
% With a little I can probably have output from gdb within a couple hours.
Good luck, then.
