Email: from it is left out (4)

My cunning email-based notification tools on our servers were working fine. I updated the Sender for their automatic emails and thought nothing more of it.

After a fews of silence from the servers, I realised somthing was amiss. After much diagnosis (and concommitant discovery of other unrelated errors) I tracked down the non-delivery of the emails to the fact that the Sender was using "" as the domain.

Turns out there is an RFC somewhere which suggests that MTAs ignore mail from "", so the mails were just disappearing into the ether!
