Thanks for your replies, citing Joe here:

I checked the ISP side, there's sendmail running as MTA and the particular multidrop box is created with an "@domain.com dropbox" entry in the virtusertable there. Looking at the mail before I'm fetching it shows there' s a "Recieved: from ... for <[EMAIL PROTECTED]>; date" (There is more stuff in the Recieved line I cut out here). So I put an "envelope Received" in my fetchmailrc (isn't this default anyway?)- to no avail, ml mails still get delivered to the postmaster. I'm just pasting the poll-part of my fetchmailrc here, maybe the position is wrong (though I don't get syntax error when running): <snip> poll mailserver.somewhere.com with proto POP3 and options no dns localdomains domain.com envelope Received user 'dropbox' there with password 'topsecret' to * here options fetchall </snip> > Probably the easiest way is to create distribution groups in > Exchange, > and use the Linux mail server to reroute mail addressed to > the lists to > the appropriate group. Ey, nice idea also. Though too much trouble at this time, I hope to get away from POP3 with an MX record in about 2 weeks time and fetchmail will be history then. Thanks for more input. Erik
