[Mailman-Users] MM doesn't send mail

[Keith Mastin]

>Hi there,
>
>it seems that my mailman installation does not send out mail. I have 
>installed Postfix as MTA on a MacOS X Server.
>
>When I create a list, I get the message that the list owner had been 
>notified of its creation by mail. But nothing shows up in the mail.log file, 
>and the mail never arrives. Posting to a list doesn't work either. Postfix 
>itself can send mail, at least by logging in through telnet 25 on 
>localhost.
>
>How can I test interaction between mailman and postfix? The Mailman 
>error log doesn't give any hints.
>
>Thanks
>Friedrich
