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. > This is the mail system at host relay.mailchannels.net. You expect mailchannels.net to be handling your outgoing mail, is that correct?

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.
