Shouldn't a secure email server check for the existance of a local
address before handling the email?

I've also had them using <> as the sender with a local acount as the
recipient. For me personally, I don't allow non-local people to relay
through my server. My server, Mercury (Winblows, but no flames
please, I'm rebuilding my Linux server to a bigger/faster system),
only allows localhost and my private network addresses to send email
to non-local recipients. This may or may not be suitable for others,
but it's how I solved a lot of my problems.
