[SLUG] Email problems

[Mike Bennett]

It could also be that they picked up on your domain and faked the From
address. This has happened to me countless times over the past few
years across pretty much all the domains that I own.

Another possible for using the address is if you were in the
addressbook of a compromised machine, the virus may use email
addresses from the addressbook as From addresses to lessen the chance
of rejection.

Unfortunately, there isn't really much you can do about it if it is a
faked address so your best bet is just to ignore and try and filter as
much of it out as possible.

Hope this is some help,
Mike
