[Dovecot] cutting everything after @

[Juraj Bednar]

Hello,


 I am migrating one server to dovecot. The only problem is, that users
 have logins with @domain as part of their user name. I want to use pam
 auth (for other reasons, if only for dovecot, I would use mysql, but I
 need the same password db to be used for other services, like samba).

 Is there a way to allow this type of login? Just cut everything
 beginning with @. I can change the source code, but then I don't get
 nice automatic upgrades.

 Or can this be done easily with PAM? 

  Thanks,


   Juraj.
