Squirrelmail login issue (ISPConfig, dovecot, full username)

Hello all,

I've succesfully installed CentOS 5.0, ISPConfig 2.2.12 with Dovecot and Postfix.
(almost) Everything is working. I can send/receive emails from various domains (using pop and pops). I'm using full username: [email protected]

I've installed the Squirrelmail package and I can't log in. I've tried using [email protected] and domain.com_user (I've changed web[ID] for [DOMAIN] so I can login with user@domain format string), neither work.

When I try to log in as [email protected] "tail -f /var/log/maillog" shows:

May 16 20:56:52 mail dovecot: imap-login: Aborted login: user=<_domain.com_user>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured

As you can see, there is an underscore as prefix of the domain, which shouldn't be there. I couldn't figure out why is this happening, that's why I'm asking here.

Hope that someone can help me with this.
Thanks in advance.

 

Till, maybe I didn't explain myself clearly.

The usernames for ISPConfig and for the O.S. are like "domain.com_user1"
I did all that extra configuration so you can have you email client send/receive email using "[email protected]" as the username.
It's working fine from the email client, but I can't log in in Squirrelmail ("wrong username or password").
So, there are not usernames with the character '@'.

/var/log/maillog shows:

May 16 20:56:52 mail dovecot: imap-login: Aborted login: user=<_domain.com_user>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured

As you can see, there is an extra '_' that is added at the beggining of the username. I don't know why this happens.
For what I've read in these forums, if I install dovecot and configure it for "[email protected]" usernames and then install squirrelmail, it should work without any modification.

Hope I was more clear this time.
Thanks for your help.

 

Yes I did.
Maybe this issue is in this last version, and not in the previous ones ?
