Hello folks...

Here on the company that I work, we already have a "pure" postfix mailserver installed...
On this server, we have some rules on smtpd_sender_restrictions, like that:

reject_unauth_pipelining,
permit_mynetworks,
permit_sasl_authenticated,
check_sender_access hash:/etc/postfix/client
reject_non_fqdn_sender,
reject_unknown_sender_domain,
reject_sender_login_mismatch,
reject_unauth_destination,
permit

On /etc/postfix/client, I put some domains that I block using REJECT statement...

Then, my question is very simple... How can I apply the same rules to Zimbra Server???
It's possible???

Thanks for any kind of advice.
