 Like good ole boys lets try it out and see where we go.  The simplicity of the 
Forum is what is appealing - so lets heed Artin's path and take it from there?  
I suggest we don't discuss this any further.

The pulse and heart of the guidelines are in the following two paragraphs.  
They are only 2-3 lines, in my judgement, they are highly demanding and puts 
lots of pressure on members to comply. 

4. The group is not moderated: each posted message is self-moderated as each 
member strives to preserve harmony among its peers, ensures that their postings 
conform to non-adversarial norms of discourse and upholds accurate 
representations of facts and events. Members monitor and regulate collectively 
the flow of exchanges for quality.

  

5. Members agree to refrain from questioning a member’s sincerity or integrity 
by speculating on their character or personal motivation for advancing an 
opinion or fact.

The updated 24April Guidelines are attached as a proposal for collective 
perusal.  They capture essentially the same goals as before with improved 
wording. The disclaimer paragraph 8 is new.  We can discuss them for a few days 
for further revisions. Once adopted, we will place them on the group’s website.

This seems very unlikely to be a mailman problem at all.

If for some reason somebody tries to blame it on Mailman and you want
more help, please be more precise about "all my member emails".  What
we see here is *one* post that bounced for a list of *several* email
addresses.  I don't want to guess whether you mean *all* posts are
bouncing to *everyone* or that it's a subset of posts or a subset of
addresses that are bouncing -- there are various mechanisms that could
cause the problem, and the exact set of mails that are bouncing will
help to distinguish them.

You expect mailchannels.net to be handling your outgoing mail, is that
correct?

This is from the MTA at mailchannels, so I can't be 100% sure, but it
looks like the remotes are rejecting your mail as soon as
relay.mailchannels.net tries to connect, and they don't actually talk
to relay at all.  The remotes have definitely not seen your mail, so
it cannot be a DKIM, DMARC, or content filtering problem, and if
"initial server greeting" means what I think it does, it hasn't seen
HELO yet so it's not SPF either.

The problem with this email is a mailchannels problem.  If others are
bouncing in different ways, it might be something else, even Mailman.

I forwarded only one of the bounces, check the list on this link: 
https://www.dropbox.com/s/auuylwltwjpvqxo/MM2.jpg?dl=0 

The attachment mentions the following and it's different for each 
bounce. Mainly *Lost connection while receiving the initial server 
greeting*.
I have never encountered such bounces with my regular email, that's why 
I was pointing to MM, but I maybe wrong.
