[Dovecot] problems with authentication

[Paul Aguirre]

Hi, I have some problems

I'm using fetchmail to get my mail from the server to
a local server, but the problem is that my user name
of the mail is "user at virtualdomain" and I can't make a
system user with "@" on centos.
So, I want to know how can I tell to dovecot the user
"user at virtualdomain" is associate to a sistem user
"user.virtualdoman". Or if any one knows another
solution.

Thanks
Paul
