Default Issues with Postfix, Courier, MySQL And SquirrelMail after server crash

I'm an absolute newbie to unix so pls be patient ;)
I have been assigned to try and make a Postfix mailsystem work again. What happened is that the server crashed (HDD damaged/replaced) the files were restored from backup. Of course postfix doesn't work anymore.
I tried to follow the documentation the person who set this up initally also followed: http://www.howtoforge.com/virtual-us...ebian-lenny-p2 however with not much luck. Every time i had a problem or ecountered an error message I looked up google and got to the next step, up until the point where i can't get answers anymore from google.

The problem now is that I cannot get into SquirrelMail (ERROR: Connection dropped by IMAP server) with any of the active accounts and the only error message I get from the mail.log is this:

Code:
May 30 23:08:37 srv1 imapd: Connection, ip=[::ffff:127.0.0.1]
Let me know if you need more information or the content of any file and I'll answer as soon as I can as I'm trying to figure this out for 2 days now (the whole weekend) and don't seem to get to the end...

Any help would be much appreciated! Thx a lot in advance!

EDITED: almost forgot something: mailx delivers the message, telnet localhost 25 is answering ok too, can logont to mySQL fine, tables seem to be ok...

EDITED2 (more info): Extract of my /etc/postfix/main.cf (I replaced the real domain names by mydomain.eu, myotherdomain.com, and mythird-domain.com, and the password by Pa55word everywhere below):

Code:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version

# line of that file to be used as the name.  The Debian default
# is /etc/mailname.

You need to have
Code:
amavis unix - - - - 2 smtp
        -o smtp_data_done_timeout=1200
        -o smtp_send_xforward_command=yes

127.0.0.1:10025 inet n - - - - smtpd
        -o content_filter=
        -o local_recipient_maps=
        -o relay_recipient_maps=
        -o smtpd_restriction_classes=
        -o smtpd_client_restrictions=

        -o smtpd_recipient_restrictions=permit_mynetworks,reject

        -o strict_rfc821_envelopes=yes
        -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks
        -o smtpd_bind_address=127.0.0.1
at the end of /etc/postfix/master.cf.

Default thanks but still no luck...

Thank you falco for the quick answer, however after adding those lines and restarting postfix, i can still not logon to squirrelmail using mydomain.eu/squirrelmail and webmaster@mydomain.eu

error message by SquirrelMail is still:

Are there any other errors in mail.log?
What's the output of
Code:
netstat -tap
?

In your authdaemonrc turn

DEBUG_LOGIN=0

to

DEBUG_LOGIN=1


You might get some more information on what is happening.

Default is this relevant?

DEBUG_LOGIN was not part of the file, so i added it at the end, however nothing changed in the mail.log - is this supposed to put the logs somewhere else?

in the meantime i realized something is happening at times i don't touch anything and it repeats almost always at the same time, once at midnight and another time at 6.25 am:
