Header Translation doesn't work for all emails
Header translation doesn't work for all emails.
If header translation isn't working for certain emails, check out your aliases.
Header translation only applies if mail is FROM a local account, TO a remote account. If a message is in the remote queue but translation did not occur, possibly an alias is set up so that MDaemon thinks it is also from a remote account. This could happen particularly for AV update messages or other messages generated by MDaemon.
To prevent this from happening, have the AV messages come from an email address that MDaemon doesn't recognize as local (such as the address that the alias points to).
