[Mailman-Users] address problem

[Jim McKay]

I'm using

* Mailman 2.1.9.-4.e15.i386
* Redhat 5.3.03.i386
* sendmail 8.13.8.2.el5,i386

I'm experienced with Mailman with BSD for sometime (a couple of years)  
but the first time with Redhat on a completely different server.

For this example/problem,

my host is    wall
Domain is   ss.uic.edu
so I have    wall.ss.uic.edu

Sendmail is fine and emails come and go with mail sent and received  
from user at wall.ss.uic.edu

I've used RPM to install Mailman.

I've created a list  called techies with subscribers on everything  
from in-house to gmail.

When as a subscriber I send email to techies at wall.ss.uic.edu  the mail  
is  arrives at users inboxes as being from techies at ss.uic.edu with  
"wall" left off.

On the Mailman admin page for "Techies" , under "General Options", I  
have "Hostname this list prefers for email" set to wall.ss.uic.edu and  
it still leaves off wall.

I've been through mm_config.py and sendmail.cf for days and simply  
can't find what's wrong.

I can live with it if I just want to have broadcast lists but I also  
need to have lists where people can reply.

Any suggestions or ideas.  Thank you very much.

Best wishes and many thanks for your consideration.
