I fear that we may have lost track of the original question about e-mail
posting problems.  I figured I'd see about restarting this discussion so
that we might solve Arnie's problem.

Basically, when Arnie tries posting to the BLUG list I get a bounce
since the list can only determine that the message is being sent
from the e-mail address "arnie".  Upon examining his mail headers I find
the line:

   sender:  arnie

which obviously is not a complete e-mail address.  The list bounces the
message since it only allows posts to come from subscribed e-mail
addresses.

I've been seeing more and more of this line showing up in peoples' mail
headers, and quite often the address given in this line doesn't match the
address that the person actually is using.  Whenever this happens the
listserver (Mailman) rejects the message.

Anyone know why we are now seeing this header line?  Where is it being
generated - in the mail transport agent (sendmail, etc.) or in the clients?
