Since you have "reject_unauth_destination", one can only conclude that "gmail.com" matches either some entry in "$virtual_alias_maps" (since you don't have an explicit empty setting for virtual_alias_domains) or it matches some entry in "$virtual_mailbox_domains". Report the output of: $ postmap -q gmail.com $(postconf -hx virtual_alias_domains virtual_mailbox_domains) -- Viktor.
