[SOLVED] Postfix: Forbid destination servers

[aleix]

Hi everybody,

I have a MailServer configured with Postfix and Virtual Mailboxes with MySQL.

I would like to add and option which forbid the users of the office of sending emails to some especific servers like HOTMAIL and YAHOO.

I read abous "access" (man 5 access), but I don't know exactly how to get it.

Any ideas?

Thanks!

Aleix

maybe this parameter

smtpd_sender_restrictions =

smtpd_sender_restrictions = - Google Search

Thanks jledhead,

It worked!

Finally someone suggested some more things and I tried this:

Create /etc/postfix/access

Add:
yahoo.com REJECT

or replace REJECT with whatever action you are looking for

run:
postmap /etc/postfix/access

Add to /etc/postfix/main.cf under smtpd_client_restrictions
check_client_access hash:/etc/postfix/access

thanks again!
Aleix
