One of my clients is getting hammered big time with NULL MAILFROM. They
are all NDRs from all over the place. Yesterday 56% of his mail was NDRs
Total Messages: 3009
TEST # FAILED Percentage
NULLMAILFROM.................1680.......55.83%
I had originally thought that punishing NULL senders would help with
some SPAM messages that I saw coming in but how can you deal with this?
I would want to let legitimate NDRs in but not these
The NDRs are bouncing back to users like [EMAIL PROTECTED] and other such
fictitious addresses. This domain is not a local IMail domain but rather
a gateway domain so I have no way of checking against a userlist.
Any thoughts?
Thanx
Goran
