I configured EIMS on my box to handle outgoing mail - it seemed a good idea, saving me a bit of grief on outgoing mail.
However, the log showed me within a day or two that the server was apparently being used to relay mail for others, although I had checked off the boxes that should have restricted sending mail to known IDs - in fact, only this one.
Needless to say I have discontinued using it. Can anyone guide me about correctly configuring SMTP?
