Not just Mailman. All services that return your mail to you with the same Message-ID will be discarded.
the list receives my post and hyperkitty also archives the post, but I don't receive my own post. I have read that it is Gmail's will to automatically discard my post.
That is correct. They're quite dug in to their foxholes on this one.
Is there any way around this insane choice?
I haven't tried it but you could try setting up an alias, or failing that a separate Gmail account just for the lists. I'm not sure what happens if you use GMail as your MX (ie, access the IMAP and submission ports) and provide your own MUA, for that matter.
I get a couple hundred emails a day to my GMail account, and simply don't find it useful for large scale email processing. I could live with the lack of own posts from mailing lists, but the butt-headed insistence on top-posting I can't abide.
