I got bit by this bug yesterday after an upgrade to courier-mta. I had a temporary and empty /etc/aliases file that had been placed there while trying to resolve another unrelated bug. Because the upgrade script apparently ran the newaliases script, it cleared my valid compiled aliases. I didn't notice this until someone complained that mail to me was being rejected with a 550 User Unknown error message.
I lost mail because of this. That's bad. -- # Jesse Molina # Mail = [EMAIL PROTECTED] # Page = [EMAIL PROTECTED] # Cell = 1.602.323.7608 # Web = http://www.opendreams.net/jesse/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
