Hello,
I'm noticing a fair amount of spam coming into our system where the
sending server is using MAIL FROM: <#@[]>.
Is there a quick an easy way to block this using tcpserver and/or
rblsmtpd?
I would like to setup something like:
RULE:allow,RBSMTPD="Domain of sender address does not exist." (This is the
same as Sendmail does by default.)
But I can't seem to get the rule working correctly.
Any pointers, or am I going about it the wrong way? Perhaps I should be
using procmail instead?
