Once we set up routing for [EMAIL PROTECTED], it was obvious that all list
messages have a sender envelope of [EMAIL PROTECTED] So I've had to modify
my conditions. The router errors_via_isp below is intended to look for
Mailman traffic which originates from the list, by comparing the envelope
sender and From: headers.
If those match, then the email should be handed to the ISP mailserver. (Our
aim is to use our mailserver for handling priority mail rather than bounced
spam.)
The config below seems to work, but I'd appreciate any critique or
suggestions.
Thanks for your help so far!
