On my Exchange 2000 box, the callout works - Exchange rejects syntactically
invalid sender addresses at SMTP time. It also rejects syntactically invalid
recipient addresses at SMTP time, but accepts and then generates bounces for
unknown recipient addresses.
I believe Exchange 2003 can be configured to do more thorough recipient
validation at SMTP time.
