Please post your config values. But I suspect you have your main domain defined in "local_recipient_maps" or "mydestination" so it's looking up that username and finding a match in the local password database. But please post your configuration (postconf -n) so we can look at it. SH> I have tried restarting both postfix and dovecot with no change in the problem. It won't change, because of how you have postfix configured to do user mailbox lookups. SH> Do we maybe need to get rid of the actual vmail box file?
