[Dovecot] system accepts my domains without point

[Esteban Torres Rodriguez]

I have postfix+ dovecot + ldap (AD).

my system accepts user at domain as user at domain. as user at domain.com. To
send as much to create the mailbox when I login to squirrelmail, for
example.
Problem is postfix, dovecot or from AD?

Someone can help me?
