I've got a user reporting to me he's getting dozens of daily messages in
his postmaster account voicing a standard 'invalid user message, where
his own address is the invalid user.  Below is a sample of what looks to
be a block of three messages going to him.  The first IP is my mail
server, the other is an AT&T broadband dialup (cable modem?) IP.

I don't know imail logs well enough to say for sure... whats going on
here?
Without seeing the full Received: headers, can't say for sure.

Probably some forging of his inane computerd.com domain as sender of spam, so his postmaster account is getting the bounces, whatever.

Sending to an Imail domain is never "relaying", it's simply local delivery.
