It's not uncommon for spammers to spoof themselves as coming from the
domain they're trying to send to -- on many sites that will get them
past quite a lot of the anti-spam functionality.

However in your case, I think something may have written a lot of
garbled stuff to your /var/log/maillog, and the daily scripts are
getting confused and thinking those are e-mail addresses.

Either that, or a machine, either in your domain or belonging to
someone who corresponds with you by e-mail, has caught a virus and is
scouring its hard drive for anything that looks even vaguely like an
e-mail address and bombarding you with infected messages.

Quite a few of those addresses look a lot like message IDs to me,
which fits with either of those scenarios.

	Cheers,

	Matthew
