Many thanks Nick and also Jim and Bob for your advice so far;
You've all mentioned VERP and related issues, which I am doing my best
to understand. Even though what I talk about below seems to ignore my
understanding of VERP, I'd be grateful if you could stick with me ...
Regarding your smtp question, Nick; I believe mailgust has been
'temporarily/partly' coded to just absorb any bounces which come back to
the mlm. It's acknowledged that the software is incomplete in this area,
including my issues with the sendmail sending.
I was talking to the developer yesterday although he is committed to
paid work for now, and he asked a question which indeed I have
considered but chose to ignore so far - if I am having trouble with mail
delivery errors going directly to list zubscribers, how could the
current mailgust state be causing this? ie, the list posting address
appears in the list headers as the Return-Path, but I know for sure that
the bounces I and others are experiencing are definitely not being
remailed out through the list.
Lee, could you put an example of a message posted to your list on a
website somewhere? With full headers, saved as a text file? All received
lines/from lines/return path/etc. visible. Curious to see what this
