No issues here.. IOS 12.0, Mail app. I get to see Reply all option when trying to reply.

That's not a valid test.  Mailman is modifying the header of some messages and not others.  For the message from Mark that you tried replying to, Mailman had not modified its header, so the reply-all works correctly.  You can tell this because the From field is not of the form "From: [name] via Tech-Talk <tech-talk@aps.anl.gov>".  I haven't looked closely, but I believe Mailman is making the decision of whether or not to modify the header based on the DMARC configuration of the *sending* domain.  (I haven't investigated that, so I could be wrong.)

Anyway, to see the behavior we're talking about with iOS Mail, find the exact message being discussed

  From: =?gb2312?B?y+/M7NCl?= via Tech-talk <tech-talk@aps.anl.gov>

  To: "tech-talk@aps.anl.gov" <tech-talk@aps.anl.gov>

and try doing a reply-all to it.  You will not have a "Reply All" choice.  (The name of the sender in the From field will display as Chinese characters in iOS Mail.  What I've shown above is the raw header From field which uses a MIME encoded word for the name.)
