I've switched a very old and heavily used sendmail server over to postfix for maildir support.
I'm having trouble with the aliases table which holds some 200 aliases. Some are written as:
"username: username, username, username"
whereas others are written as:
"username: firstname.lastname@example.org, email@example.com"
some of which are local virtually hosted domains. this worked fine with sendmail, but seems to fail with postfix. Is there a workaround?
