Hello
I receive periodically some spams that pretend to be
from my domain.
Looking in emaila headers I can see where the email come from
Received: from 174.subnet222-124-154.static.astinet.telkom.net.id
(unknown [222.124.154.172])
Of course the header has been rewrited but is there a possibility with
postfix
to refuse that kind of emails that comes from an explicitly outer IP
address
but pretend to be in my domain ?
there are many many many things you can do.
- use one or more of
reject_rbl_client zen.spamhaus.org
reject_rbl_client bl.spamcop.net
reject_rbl_client psbl.surriel.com
- reject any mail from
.astinet.telkom.net.id
- tell us if you're talking about envelope sender (mail from) or the
from header.
