[Dovecot] auth_username_format

[Sergio Souza]

I configured in the archive dovecot.conf the parameter 
auth_username_format = “%Ld_%Ln” because the users of my server have 
access yours e-mail accounts based in /etc/passswd where they are 
registered in format domain.com_user. This configuration work without 
problems via pop3 and imap (squirrelmail). My server is CentOS 5.0 and 
dovecot is 1.0.rc15.

The problem that occurs currently is: when the users go to have access 
the interface of change preferences (ISPCONFIG) where the supplied data 
of authentication are not the data of the email account (eg. 
user at domain.com) and yes of /etc/passwd the dovecot inserts underscore 
before the domain (eg. _domain.com_user) when it would have to make this 
only between the domain and the user.

Exists a way to solve this problem?

Thanks in advance.
