Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail

Can you try to raise PHP's memory limit in the php.ini file and restart Apache afterwards?

 

Thanks.

I have raised the memory limit from 16MB to 64MB and restarted the apache server but same 'blank' page again.

This could be fun, a new problem!

Hi,

I've set up this mailserver with the tutorial, and it worked fine after intensive testing. Now, the system is live and it keeps on crashing. However, I cannot find an error log anywhere, don't even know where to look anymore..

What happens is, at some point, the server just stops delivering mail, or even processing mail? Users cannot send/recieve mails.. They can log in though and everything looks fine. After I restart *all* processes (since I don't know which is failling), the server start delevering the mails (so the mails get in, but not delivered). I think they are stuck somewhere in either spamassassin, clamv or the thingy that actually delivers the mails (is it maildrop?). The only thing noticable in the logs, is that there are no more entries as soon as the ghost deamon crashes (don't know which one).

Any ideas?

thx,
wybren

 

Did you check /var/log/mail.log?

 

well yes, only thing funny in these logs are:

Sep 1 06:57:42 cantharis postfix/error[30240]: 1AEBA18907B5E: to=<[email protected]>, relay=none, delay=11524, delays=10923/600/0/0.02, dsn=4.4.2, status=deferred (delivery temporarily suspended: conversation with 127.0.0.1[127.0.0.1] timed out while receiving the initial server greeting)

And this a lot. So, it is the delevery thingy that is not responding, but why?

 

What's the output of

Code:

netstat -tap

?

 

Code:

Note: At this point, everything is running as it should. I'm also beginning to suspect amavis-new (it used 100% CPU today, a process which I had to kill)

 

HowTo depedencies

Sorry to intrude in the thread but I have a question about the "Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.04 LTS)" tutorial.

The preliminary note states that "...This tutorial is based on Ubuntu 8.04 Server (Hardy Heron), so you should set up a basic Ubuntu 8.04 server installation before you continue with this tutorial (e.g. as shown on the pages 1 - 3 in this tutorial: The Perfect Server - Ubuntu Hardy Heron (Ubuntu 8.04 LTS Server))...". Does this mean that you have to follow the entire Perfect Server tutorial and install and setup everything or that pages 1-3 are enough?

 

Do you see any errors in the mail log when you restart Postfix and amavisd?

 

Pages 1 - 3 are enough.

 

unable to login using squirrel mail or telnet

hi,

i've followed all the steps in the howto, but i can't login using squirrelmail, mail.log says:

Code:

imapd: Connection, ip=[::ffff:127.0.0.1]
imapd: LOGIN FAILED, [email protected],ip=[::ffff:127.0.0.1]
imapd: LOGOUT, ip=[::ffff:127.0.0.1], rcvd=58, sent=332

trying to connect using 'telnet localhost pop3' i get:

Code:

courierpop3login: Connection, ip=[::ffff:127.0.0.1]
courierpop3login: LOGIN FAILED, [email protected],ip=[::ffff:127.0.0.1]

However, using postfixadmin i am able to send emails, i can also receive mails from my gmail account.

Has anyone a hint how i could track this down ?

 

ok, i figured out the solution myself, the module was simply not installed...

now i'm struggling with a different error when logging in with squirrelmail:

Code:

Access denied for user 'mail_admin.'@'localhost' (using password: YES)

What is strange here is the . after mail_admin. i've double checked the authmysqlrc file and dot is definitely not there.

Anyone knows what could cause this ?

 

None, btw, the service was down today, while it was, I did the netstat thingy:

Code:

tcp        1      0 localhost:10024         localhost:51173         CLOSE_WAIT  -
tcp        1      0 localhost:10024         localhost:51810         CLOSE_WAIT  -
tcp        1      0 localhost:10024         localhost:36522         CLOSE_WAIT  -
tcp        1      0 localhost:10024         localhost:56246         CLOSE_WAIT  -
tcp        1      0 localhost:10024         localhost:51483         CLOSE_WAIT  -

Quite a lot of these..

 

I'd search all your configuration files for "mail_admin.".
