If inbound and outbound are separate, you might be able to get away with "from:my.domain REJECT" on the inbound.
Can I block the entire domain like "From: my.domain REJECT" ?Yes, I believe so.
From:my.domain ERROR:5.7.1:550 Unacceptable sender domain
What I want to achieve is that some ip ranges should be excluded from this rule.
I got the request from management to block e-mails with fake sender address with the
own address. Therefore I have 2 questions:
