My mistake. You are not using Sendmail.py (you have to do several,
non-default things to enable it and make it useable). I was typing too
quickly and carelessly. I meant Mailman/Handlers/SMTPDirect.py, not
Sendmail.py.

However, I think you said that your problem, if it is caused by the
envelope sender, is limited to recipients in your own ISP's domain.
Perhaps you could 'fix' it in some other way. I think you first need
to determine, perhaps with the ISP, exactly why these messages aren't
being delivered. Since your Sendmail MTA reports no error, it somehow
is occurring within the ISP. If it is the fact that the From: is from
a user in the ISP's domain, and the envelope is not, it would seem to
say that no one could post to any Mailman (or perhaps other MLM) list
from that domain and have their post delivered back to anyone in that
domain. It doesn't seem that the ISP would really want that.
