If you have the SMTP Security set to 'Relay for Anyone', this would cause
IMail to accept ALL email, regardless of the username or domain (the email
address) you send to. So IMail accepts (your client says 'delivered'), but
once IMail tries to send the message, it cannot (user does not exist!), so
postmaster bounces it back to you. Only if you have a different SMTP
Security/Relay, setting (stop/start the SMTP service if you change SMTP
Security settings), will IMail, respond during the clients send attempt,
with the 'unknown user' message. So your message would now not be accepted
by IMail, using the different SMTP Security setting. Note: Relay for
Addresses is the most secure, Relay for HOSTS, may still accept the message
(only checks the part after the @), but if it does accept the mesage,
postmaster will bounce it, later (I think, have not tested this recently, so
not positive).
