[Mailman-Users] Mailman and virtual mailhosting (postfix)

[Jens Meyer]

Dear Mark, hello all!

Thank you very much for your detailed reply to my request from June. 
Your help is greatly appreciated - but unfortunately I had no time to 
check this out until now due to work-overload and holidays.

My system accepts mails for listname at lists.myserver.de without problems. 
The only problem is that I can not use the internal redirection from 
mailman to listname at myserver.de without (internal) postfix-warnings 
because the domain myserver.de is used by the virtual mailhosting also 
(see my last post).

So one solution would be to "ask" mailman to redirect all emails not to 
listname at myserver.de but to listname at MAIL.myserver.de.

Do you think this is possible or is there another solution for my problem?

Kind regards,

       Jens
