So let's look at your actual problem without the noise around it:

Nov 30 22:57:04 jupiter sendmail[11058]: eAULv4S11058: <test-admin@remco.homeip.net>... User unknown Nov 30 22:57:04 jupiter sendmail[11058]: eAULv4S11058: from=<test-admin@remco.homeip.net>, size=1002, class=0, nrcpts=0,

proto=ESMTP,

...

daemon=MTA, relay=IDENT:28@localhost [127.0.0.1]

...

Very strange because I can send a normal mail to

<test-admin@remco.homeip.net>

...

which is delivered.

Which machine is jupiter? Which machine is remco.homeip.net? Are they the same?

Yes, the same machine. "remco.homeip.net" is the name from the internet. "jupiter" is the hostname in my local domain.

So if you can send a mail to test-admin@remco.homeip.net as some user, but the mailman scripts cannot, I have no idea what the problem might be. It must be some very strange error in sendmail depending on some sender context, and reporting the error wrongly, or else some subtle error in the SMTP dialogue. I'd probably watch the SMTP session with truss/strace/ktrace or whatever and see exactly what Mailman is sending, and duplicate that with a telnet to port 25.

-Remco

PS I'm on the mailman-users list.

Yes, and so am I.
