A bounce message will have an empty envelope sender, so I file
those separately via procmail. This is the rule I use:
#
# Bounces
#
:0:
*(Return-Path:).*(<>)
.Automated.bounces/
I look at the bounce mailbox every few weeks. But mostly I know
when there is a flood of them - either I get one message meaning it
is probably legitimate. Or I'll receive a few thousand one day -
meaning I've been spoofed.
I believe it is possible to sign outgoing messages to detect legitimate
bounces and dump bogus ones - but I've not tried that.
