Hi to all,
Just a question, there is any method to limit the outgoing mails ?
Something like domain.com allowed, domain.net not allowed, or
u...@domain.com allowed, u...@domain.net not allowed. And this can be
done for each user?
Postfix enforces such limits while RECEIVING mail:
http://www.postfix.org/SMTPD_ACCESS_README.html
To stop mail from out-of-control web applications, use spam filters
as discussed today in the "lost credentials" thread.
If is possible, there is any web based or similar tool to manage this thing?
Gui support is not included.

I use this procedure to acomplish who one domain can send internet email
and one domain can send only local mail.
r...@imss:~$ vi /etc/postfix/main.cf
smtpd_recipient_restrictions =
check_sender_access hash:/etc/postfix/Custom/sender_deny
permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination
smtpd_client_restrictions =
permit_sasl_authenticated,
reject_unknown_client
smtpd_restriction_classes = local_only
local_only = check_recipient_access
hash:/etc/postfix/Custom/local_domains, reject
r...@imss:~$ cat /etc/postfix/Custom/local_domains
