virtual users and domains with postfix courier mysql and squirrelmail ubuntu10.10

hi..im new with ubuntu.. using this article to set up a mail server: http://www.howtoforge.com/virtual-u...x-courier-mysql-and-squirrelmail-ubuntu-10.10

I've done everything exactly as in the tutorial and i can see the login page.. but when i try to login using [email protected], i got an error page "ERROR: Connection dropped by IMAP server"

now i need the solution for this problem.

 

i have the same problem, using debian as OS
http://www.howtoforge.com/virtual-u...courier-mysql-and-squirrelmail-debian-squeeze

the configtest.php suggested by squirrelmail gives no error but logging in returns the mentioned error. Already sent a welcome mail to create directory, but nothing...

 

Are there any errors in your mail log (in the /var/log/ directory)?

 

I get a lot of these errors:

Apr 9 13:32:25 srv1 postfix/qmgr[14343]: 07DFF201217: from=<[email protected]>, size=435, nrcpt=1 (queue active)
Apr 9 13:32:25 srv1 postfix/qmgr[14343]: warning: connect to transport private/amavis: No such file or directory
Apr 9 13:32:25 srv1 postfix/error[31074]: 07DFF201217: to=<[email protected]>, relay=none, delay=75776, delays=75776/0.02/0/0.04, dsn=4.3.0, status=deferred (mail transport unavailable)

The problem might be, that the mail dir has not been created yet, because the fist message could not be send.

EDIT:
I managed to fix it. There was a configuration error with amavis... Now the log says that the message was send.
But when I try to login I get Error 500. There seems to be something wrong with squirrelmail...

 

Are there any new errors in your mail log?

 

This is what I found in mail.log after trying to login:

Apr 11 08:33:06 srv1 imapd: Connection, ip=[::ffff:127.0.0.1]
Apr 11 08:33:07 srv1 imapd: LOGIN, [email protected], ip=[::ffff:127.0.0.1], port=[37607], protocol=IMAP
Apr 11 08:33:07 srv1 imapd: LOGOUT, [email protected], ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=30, sent=392, time=0

 

mail log

this is my mail log.. i already install virtualbox4.0 and create [email protected]
already forward first email to that account but still have error.

 

I guess that mail didn't arrive. Can you send another email to that account and check if there are any errors in your mail log when you send that mail?

 

already send another email to [email protected][/email] but still have the same problem... Im not sure what are the problems..

here is mail log after send welcome mail

 

Does mail.example.com exist in DNS (or is it listed in /etc/hosts)?

 

im not sure about this. how to check back what ive done? im using this tutorial to setup the server http://www.howtoforge.com/perfect-server-ubuntu-10.04-lucid-lynx-ispconfig-2

and mail.example.com was not listed in my /etc/hosts.

 

Does

Code:

dig mail.example.com

return anything in the Answer section?

this is what i get when type dig mail.example.com

 

There's no A record for mail.example.com, so you must create one.

 

how to make A record for mail.example.com?

 

You must do this on the nameservers that are authoritative for example.com. You can find out these nameservers by running

Code:

dig ns example.com

If these nameservers belong to your domain registrar or ISP, chances are that they provide a web interface where you can create the A record.

this is output after type dig ns example.com.. im not sure this nameserver belong to my domain registrar or not.

 

Did you replace example.com with your own domain?

 

no.. example.com is was my domain

 

That's not possible. example.com is a registered and existing domain. You must use your own domain.
