Jason,
When using 'Relay for local hosts only', ANYONE who uses '@yourdomain' in
their return address, can send email through your system. So if I change my
reply address to '[EMAIL PROTECTED]', I could use your system and send email
to anybody, even if dand is not a valid user account.
I did just try this with your server and was not succesful in sending a
message to myself. This implies that you have changed the Relay settings.
Since I could not do it this way, the only other method that someone might
use, would be to have the recipient be a user in your domains, and have a
BCC that includes outside addresses. IMail would accept the message (since
it is for a valid user) and IMail then tries (and is succesful) delivering
to the BCC address(es).
