I am trying to make it so that postfix takes specific actions when
spam "from" my domian externally arrives.
smtpd_recipient_restrictions / reject_unknown_... looked prommising
but I dont see how to work it with the information given.
When a new message arrives with [from: somt...@mydomain.com]
[to:somt...@mydomain.com] and sender ip address does not = $mynetworks
i want to send connecting pc's ip to external scripts if possible and
the least reject the message.
reverse dns lookup from my internal dns server would work as well.
eventually I may be interested in having tls or something authenticate
external users to send from mydomian but that is not a big concern
right now. If need be vpn will solve that need.
any suggestions are appriciated. If I missed a how-to or something I
appriciate the links. I dont always figure the best key words to find
these things.
In main.cf:
smtpd_recipient_restrictions = permit_mynetworks,
check_sender_access hash:/etc/postfix/my_own_domains,
reject_unauth_destination
and in my_own_domains:
techsoft3d.com REJECT
etc.
Or one of the other possible actions; there are quite a few, read the
man page for details:
