[courier-users] courierpop3dsizelist - suggestion
I have a simple optimisation suggestion for the new courierpop3dsizelist mechanism. At the moment it is written out as soon as the mailbox is opened. I suggest delaying writing it out until the mailbox is closed (excluding any DELEted items) or the session dropped. The benefit of this is that in the normal case where a client downloads and deletes all messages, no courierpop3dsizelist file needs to be written at all - thus there is no overhead in terms of disk space, inodes, and disk operations to maintain it. As an additional optimisation it could be not written out if no changes have been made (i.e. for repeated polls of a mailbox when no new items have arrived) Regards, Brian. --- This SF.NET email is sponsored by: FREE SSL Guide from Thawte are you planning your Web Server Security?

[courier-users] Quota implementation ?

[courier-users] Courier-imap won't query mysql at localhost
Hey all Im trying to setup a virtual domain mailserver but it simply won't work. I made mysql log to sql.log and watched as I tried to login but nothing happend in sql.log and the mailclient said I didn't have the right username og password. Courier-imap wont query mysql. I've tried telneting: $ telnet localhost 110 Trying ::1... Connected to localhost. Escape character is '^]'. +OK Hello there. user [EMAIL PROTECTED] +OK Password required. pass fake -ERR Login failed. quit +OK Better luck next time. Connection closed by foreign host. As you can see, telnet gives the same error. And nothing happend in sql.log. Im hoping you have had a simular proplem or can tell me how to debug courier-imap. Im out of ideas. I've also tried to compile courier-imap several different ways but always get the same thing. The config files look fine to me, authmysql is in authmodulelist and authmodulelistorig: root@office:/usr/local/etc/courier-imap# grep authmodulelist authdaemonrc ##NAME: authmodulelist:0 authmodulelist=authmysql authpam ##NAME: authmodulelistorig:1 authmodulelistorig=authcustom authuserdb authmysql authpam Im running a freebsd 4.7-stable and used ports /usr/ports/mail/courier-imap) to install courier-imap.

RE: [courier-users] Quota implementation ?
Title: RE: [courier-users] Quota implementation ? At the end of each day I scan the mail logfile to determine if anyone had bounces due to quota. I then check their maildir, see if it's greater than 15MB (we have a 20MB default quota here) and if so drop a notification email into their maildir. It's certainly not exactly what you're looking for, but it does give a customer some feedback, and also emails us a complete list of everyone who had quota-related bounces.

[courier-users] imap mysql authentication problem
For a while now, I am working on a mailserver setup using postfix, maildrop, imap and mysql. Most of it is working fine now, but I'm not able to authenticate my users with the use of a mysql database.

It's my understanding that .courier files can contain only a maildir or mda entry, correct? I'm wondering if it would be possible to also use these to respond with smtp error codes, too.. particularly something like unknown user (I forget the numerical code). I enjoy having all email to my domain come into my mailbox, but there are a handful of addresses (leftovers from lame people who type in fake addresses in icq, web forms, etc) that I'd like to explicitely deny.

[courier-users] Problem dealing with the queue
Hi list, I am having some difficulties to deal with postfix queue. There is amail serverthat is not receiving mail from my server (probably they put an ACL, because the connection times out), and because of that, my queue is growing very faster, causing delays to the deliver of every e-mail we send. 1) I need to point mx.thedomain.com to a different IP address (they have other SMTP server that does not time out with my server), so I edited the hosts files of the server, but it keeps trying to send to the old IP ADDRESS. 2) I need to put the queued messages as hold for this specific domain.

[courier-users] OpenBSD 3.2 breaks Courier, Qmail.
It's been brought to my attention that OpenBSD 3.2 can assign the same pid to different processes in the same chronological second (that is, one process terminates, and its pid is immediately assigned to a new process that's created soon thereafter). Since filenames for messages in maildirs are generated based on the combination of the pid, and the current time, in seconds, there is now a race condition that will result in loss or corruption of mail. This breaks Courier and Qmail. Example: process A delivers a message to a maildir just before process B reads Maildir/new, and A's message is moved to Maildir/cur a short time after it's been delivered, and A exits; meanwhile process C starts, and delivers mail to the same maildir; its generated filename will now be the same; so now you will have two messages with the same base filename in the maildir). This is not theoretical. This been brought to my attention after someone managed to succesfully deliver two messages with the same filename, on a piddly Athlon (as part of a Courier stress test). Let's have a round of applause for such a noteworthy accomplishment! Now, my opinion is whoever did this in OpenBSD was insane. Hey folks, let's all 'rm -f /bin/ps', because ps(1)'s output is meaningless now. Whatever it spits out, by the time you get around to typing 'kill', you may end up signaling a completely different process. Oh, and setting 'sig' to 0 in kill(2) no longer means anything either. I mean, it's just plain stupid to use kill(0) to validate a pid, do a few miscellaneous things, then try again with a real signal, right? So if you now end up bitch-slapping a completely unrelated process, it's going to be all your fault. But, what do I know... In any event, here's a patch that will apply to the current release of Courier, Courier-IMAP, SqWebMail, and maildrop. http://www.courier-mta.org/beta/patches/pid-fix/ - it adds microseconds to the generated maildir filenames.

[courier-users] courierfilter.pid not found during Courier setup
Hi, When I run the /usr/local/etc/rc.d/courier.sh startup script the following error occurs: /var/spool/courier/tmp/courierfilter.pid: Permission denied authdaemond courierd esmtpd imapd pop3d I've checked the ownership and permissions on the /var/spool/courier/tmp/ directory and it is owned by user courier with group courier with permissions 770. Is this correct? I've checked that /usr/local/bin/sendmail has the correct ownership and permissions. It is owned by root with group wheel, has permissions executable by all, and is setuid to run as root privilage. Is this correct? It seems that the courierfilter.pid file is not being created or is not found by courierfilter.pid. Something is violating the permissions. If I simply run courierfilter start I get the same permission denied error message. Is there something wrong with the above permisison settings that is causing this? Note that many of the other pid and lock files are being created in the /var/spool/courier/tmp/ directory. Is there some simple configuration setting that I'm missing that would cause the courierfilter.pid to be not created? I've started looking trough the source code to see how the pid files are created. It seems that courierfilter.c function start calls ll_daemon_start() in file ../liblock/lockdaemon.c which in turn calls funtion ll_daemon_startl() where an attempt to create the courierfilter.pid file is made. I'm guessing that this is where this fails with a permission denied. I've tried to run the strace command to confirm this but it doesn't seem to be providing enough info even with the -v strace option. Any help will be deeply appreciated as I've been attempting to get this courier beastie working for a long while now.
