Thank you for the quick response. After arjen's and Adam's suggestions, I did the following: - take the www-domains out of locals - virutaldomains: foo.com:alias-foo - created $QMAILDIR/alias/.qmail-foo-postmaster And I did not create a .qmail-foo-default with #, because I need valid bounces. I can't let the machine ack a message and then send it to /dev/null. cheers Wolfgang Rupp Network Administrator Mayr-Melnhof Packaging GmbH Floragasse 7/6 A-1040 Wien Tel: +43-1-50257-238 Fax: +43-1-50257-260
