Fetchmail trouble with mailing lists

[Erik Dörnbach <doernbach@elge.de>]

Hello people,

I'm having a Debian Sarge box here running fetchmail, sendmail, spamass-milter. Mail
retrieved by fetchmail from 2 multidrop POP accounts is delivered to local sendmail (for 
spam check) and then forwarded via mailertable to an Exchange server. Everything on the
Debian box are official (well, testing) debs.

When any user on the Exchange is subscribed to a mailing list just like this, mail will be
delivered localy on the Debian box to the account set as postmaster in the global 
fetchmailrc (running daemon mode btw). The original reciever's address is neither seen in 
any logfiles or in the postmaster mbox, just the ml address (which can ofcourse not be 
delivered).


What did I miss here?

Any suggestions appreciated...

Best regards,

Erik
