Hi there,

after installing Mailman I tried to get it running, having only some success. 
I tried a lot of things, but now I think I've got stuck. Maybe I should first 
explain, what I want to to and how I tried it:
I want to run a mailing list for our diving club, which has its own webpage 
and email accounts, but no mailinglist capability. At home I'm running my 
Linuxserver with an dyndns.org name, on which I planned to run Mailman.
Clubserver is tuemmler.de, my adress is wirts.homeip.net (internal name is 
brainware.local).
Techspecs: I'm running Suse 8.2 with postfix as mailserver. No Problems 
getting and sending mails with several emailaccounts, just works fine.

I have configured a mailinglist called tuemmler in Mailman, which is viewable 
on my webserver under wirts.homeip.net. I can subscribe to the list, get the 
confirmation mail, after confirming I can reconfirm as admin and get the 
concluding email that I'm allowed to post. Now I've created an emailaccount 
on our cluserver which is named tuemmler at tuemmler.de, to which I would like 
the clubmembers to send their emails. After fetching them from the server, i 
receive an error, that the local name tuemmler at brainware.local does not exist 
(I thought this would be handled by Mailman, intercepting those mails, but 
obviously it doesn't), so I created a local userr called tuemmler. Now those 
mails end up in the local mailbox instead of being delivered through the 
mailinglist.

So, after the long story here are my questions:
Could I setup my mailinglist, being fed throug an external mailaccount, or 
should I think again and try a competely new aproach?
If it is possible, what did I do wrong? Maybe something forgotten?

I don't know exactly what information you might need to help me, so I first 
include my mailman configuration

MAILMAN_MAIL_GID="65533"
MAILMAN_CGI_GID="65534"
MAILMAN_MTA="Postfix"
MAILMAN_LINK_ALIASES="yes"
MAILMAN_SMTPHOST="brain.brainware.local"
MAILMAN_DEFAULT_NNTP_HOST=""
MAILMAN_DEFAULT_EMAIL_HOST="wirts.homip.net"
MAILMAN_DEFAULT_URL_HOST="wirt.homeip.net"

DELIVERY_MODULE="SMTPDirect"  # this one I included after having read tons of 
mails in this list, but it seems to have no effect.

Another thing I found reading the lists is the output from postconf -n

smtpd_use_tls = no
strict_rfc821_envelopes = no

If there are other information missing I will glagly post them.

Thanks in advance for your time, and sorry for the long mail :-)
