It turns out the configuration problem was on Netcom's end. They have fixed
the problem and we haven't had anymore problems.

----- Orignial Question -----

Sun Managers,

I have a really annoying problem with my mail system.

Whenever we received mail with the return address formated as follows:

<@CUNYVM.CUNY.EDU:LISTSERV@BINGVMB.BITNET>

The mail disappears into the bit bucket and I get the following message in
my /usr/spool/uucp/.Log/uuxqt/netcomsv file:

uucp netcomsv compwrCaa20 (9/7-14:41:01,4942,0) BAD USER NAME
(netcomsv!<@CUNYVM.CUNY.EDU:LISTSERV@BINGVMB.BITNET>)

The following addresses are the only ones that have caused this to occur,
and them all seem to be bitnet addresses.

    <@mail.uunet.ca:news@xenitec.on.ca>
    <@EMUVM1.CC.EMORY.EDU:LISTSERV@EMUVM1.CC.EMORY.EDU>
    <@uga.cc.uga.edu:USERNAME@TIFTON.CPES.PEACHNET.EDU>
    <@CUNYVM.CUNY.EDU:LISTSERV@BINGVMB.BITNET>

I am running SunOS 4.1.2 on a Sparc 1. I am using sendmail for local mail
delivery and have tried, in vain, to configure it to handle this problem.
I have searched "sendmail" by Bryan Costales from O'Reilly & Associates.
I use a dial-up uucp connection to Netcom.

If anyone can help, offer suggestions, need more information, etc.,
please send e-mail to:

ju@compwr.com

Janet,

The VMS system administrator here noticed a similar problem on a VAX
using UCX SMTP code that was probably also derived from the vulnerable
(many security bugs have been found) ancient sendmail release 5. We
use Berkeley sendmail 8.6 around here, which contains many bug fixes
and enhancements, and handles relayed mail correctly. You can
download the source code by anonymous ftp from FTP.CS.Berkeley.EDU,
directory /ucb/sendmail.
