Restrict mail Server

[aleix]

Hi everybody,

I have a MailServer with virtual domains and virtual users.

Now, these 2 domains can send mails to Internet, but I would like to restrict one of these virtual domains to forbit sending emails to internet, so it can only send mails to the same virtual domain or to the other virtual domain of the same mail server.

Any ideas?

Wait guys,

maybe there is no enough information...

the MailServer is made with Postfix as a SMTP and Dovecot, and I use MySQL to create virtual users and domains.

I've read things about smtpd_recipient_restrictions or smtp_reject_classes, but I've been trying it with some file lists of emails and it doesn't work.
