202285Catching loop bounces
- Aug 1, 2006Hi,
I'm currently tweaking my Postfix setup to make it more resilient in
today's spam filled world. My primary concern is the number of bounces
being sent out as spammers try to send to non-existent users and addresses.
I've addressed the former with (relay|local)_recipients which now
correctly rejects email to invalid users. I wonder if the same can be
applied to domains because I get a lot of email to 'mail.esuna.co.uk'
but only accept to 'esuna.co.uk'. That currently bounces to a
(potentially forged) address.
Is there a similar mechanism to simply reject email to unacceptable domains?
