hello there,

i have a little tricky problem and cannot find any solution on the web.
so maybe you can help me:

i use the actual mailman v2.1.5 and sendmail 8.12.3 as mta (if this
many lists are running on this server without any troubles. but now i
got a problem with a specific email-address which will be bounced and i
don't have any idea to solve this.

the subscribed address is testuser at domain.de and the mail-log shows this
as the from-address of the mail-header:

sendmail[9815]: j12IixwR009815: from=<testuser at domain.de>, size=228403,
class=0, nrcpts=1,
msgid=<OFAD6162BE.A6A25616-ONC1256F9C.0066DF13-C1256F9C.0066F3FA at inside.
domain.de>, proto=ESMTP, daemon=MTA, relay=mail5.exozet.com

sendmail[9822]: j12IixwR009815: to="|/usr/lib/mailman/mail/mailman
bounces listname", ctladdr=<listname-bounces at mail4.exozet.com> (2/0),
delay=00:00:01, xdelay=00:00:00, mailer=prog, pri=258656, dsn=2.0.0,

(sorry for changing the origin address and listname, but it's for
privacy issues)

as you can see the message-id contains the domain INSIDE.DOMAIN.DE and
in my opinion this is the reason why the mails from this user are

Feb 02 19:45:02 2005 (9202) bounce message w/no discernable addresses:
<OFAD6162BE.A6A25616-ONC1256F9C.0066DF13-C1256F9C.0066F3FA at inside.domain
Feb 02 19:45:02 2005 (9202) forwarding unrecognized, message-id:
<OFAD6162BE.A6A25616-ONC1256F9C.0066DF13-C1256F9C.0066F3FA at inside.domain

now my question: is it possible to change the configuration in that way
to accept mails from this user. the problem is the user doesn't really
know his "real" domain name...

thanks for any given advice.
