Virtual Users And Domains With Postfix, Courier And MySQL (+ SMTP-AUTH, Quota, SpamAs

[skluz]

I just finished running through Falko's Virtual Users And Domains With Postfix, Courier And MySQL (+ SMTP-AUTH, Quota, SpamAssassin, ClamAV) tutorial which was very straight forward. Unfortunately I still haven't been able to get everything to work.

My current problem is that rather than saving email messages in the /home/vmail directory they're being saved in the user's home directory... which won't be very useful for my other domains.

I'm also not able to successfully connect via the pop connection:
link:/var/log# telnet localhost pop3
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
+OK Hello there.
user skluz@xactlydev.com
+OK Password required.
pass myTempPass
-ERR Maildir: No such file or directory
Connection closed by foreign host.
link:/var/log#

Any Ideas?

I searched through all the previous threads and didn't find any that had this exact problem... If I did miss a thread I apologize in advance.

Thanks for any help you can give.

The pop3 error occures because you had not send an email successfully to the vmail user yet.

Did your vmail users have the same username then real system users? Try to make a vmail users with a name that does not correspond to a system user.

Please compare your configuration files with the ones from the tutorial. Maybe you made a typo somewhere. Also take care about the format of the configuration files (whitespaces, tabs, ...), especially Courier is very finicky about this.

I have run through the tutorial 3 times to make sure that I don't have any typos... I did find a few whitespaces on the end of the /etc/postfix/main.cf file after ='s without trailing information. Unfortunately it doesn't seem to have changed anything. I had heard that this was important in the /etc/courier/authmysqlrc file so it had already had all of it's extra whitespace removed.

I have also tried sending email to an email user that isn't a system user. It was bounced because the user was "unknown".

It turns out that a lot of my problem was with mysql permissions. I was able to add permissions on for %, which seemed to get me past a few problems.

I then manually added the directory structure under /home/vmail in order to allow the users to successfully log into the pop3 connection. So pop3 works.

SMTP still not quite right. I'm still having the problem with the mail delivery. The SMTP system is still using the system accounts rather than the mysql information. There's definitely some disconnect here that I haven't been able to put my finger on yet.

[skluz]

okay...now I'm really confused. Email's are being delivered to the system user account, but the pop checks the virtual directory like it's supposed to.

I tried playing around with the /etc/postfix/main.cf but I'm still not able to get things delivered to the correct location.

You still not answered my question:

Did your vmail users have the same username then real system users? Try to make a vmail users with a name that does not correspond to a system user.

[skluz]

I've tried sending email to non-system users...and the emails get bounced.

The email then get's forwarded to root's Maildir.

[skluz]

At one point I had removed my primary domain from the domain mysql table. This was causing the problem.

I've added a virtual domain, and it seems to be working correctly.
So should I removed my primary domain from the main.cf file so that all the domains are virtual?

Basically all emails at xactlydev.com are not working...but my virtual domain, skluz.com, seems to be working fine. VERY ODD...

[skluz]

I think I've finally got this thing under wraps.

By removing my primary domain from the mydestination line in the /etc/postfix/main.cf I was able to get everything working as expected. I still haven't figured out the IMAP stuff as I hadn't used it before. Maybe I'll dig around with that this week.

Thanks for all your help. Keep up the great work and the great HOWTOs. I made the switch from SuSE to Debian because of your tutorial, and I'm glad to have another flavor of Linux under my belt.
