Hello List
My first time here so, please, point me any mistakes.
I need some special setup for my postfix server (running postfix-2.6.5 + mysql
on x86_64 kernel 2.6.31) with 11 virtual domains.
I have several users that does not need to send email offsite, so I've managed
to create accounts in another domain (and created a new virtual on postfix).
That far, all is set and working. The problem is that users are using the new
accounts to send mail off-site. I'm trying to figure how to block that
communication, so far testing smtpd_recipient_restrictions using a hash, with
not even a bit of success.
Last attempt, directly from postfix docs:
smtpd_recipient_restrictions =
check_sender_access hash:/etc/postfix/restricted_senders
smtpd_restriction_classes = local_only
local_only = check_recipient_access hash:/etc/postfix/local_domains, reject
/etc/postfix/restricted_senders:
internal.domain.1 local_only
internal.domain.n local_only
/etc/postfix/local_domains:
allowed.domain.1 OK
allowed.domain.n OK
My setup need to allow all users from domains listed in restricted_senders to
send and receive mail from other list of domains (local_domains).
If someone can point me any directions...
Thanks in advance
Regards
Rafael
