Hello.  We're running HoneyDanBer UUCP in a BSD environment on
Apollo HW (SR10.1).  We have three external company-related sites
that send us e-mail via UUCP.  These sites often send us mail that
arrives with a From: header that looks like so:

     From:  <site>.mentor.com!somewhere!<user>

Needless to say, replying to this mail does not work so well.
Has anybody out there seen this problem before and do you 
know what's causing it?  I have run the following programs
through /usr/ucb/strings:

    sendmail
    uuxqt
    uucico
    smail
    rmail
    uux

The only program that proved interesting was rmail:

[11 ~] /usr/ucb/strings /bin/rmail
       @(#)rmail.c
       3.1  - 87/07/15
       Usage: rmail user ...
       /dev/null
       From 
       >From 
       %s %s
       remote from somewhere   <----
       remote from 
       remote from %s
       %s -ee -f%s -i
       /usr/lib/sendmail
       pclose: status 0%o
         
I am aware that incoming mail is handled via this flow of control:

   uuxqt -> rmail -> sendmail -> local_delivery_agent

Is it possible that "rmail" is adding "somewhere" to these
addresses?  If so, why?  

Help...
