In my previous servers I have clamav+spamassassin configured in postfix, but things as, scan only outgoing emails it's not possible.

What's the best option for these two filtering now adays?

besides that this is the wrong list why should it not be possible?

• clamav-milter exists
• spamass-milter exists
• "-o receive_override_options=no_milters" exists

normally you have submission (587) for authenticated mail and MX (25) for inbound mail and both can have their own receive_override_options

our MX is a own server delivering already filtered messages to the mailstorage on a different vserver in the LAN via port 10025

the service 10025 is only reachable from one IP (the MX LAN interface) and has "receive_override_options=no_milters" while all other smtpd services in "master.cf" use their own milter setup adjusted for outgoing mail and both machines share a careful maintained bayes-database trained on one machine and deployed with rsync
