You are correct: Someone is spoofing your address for spam, or someone that
has your address on their computer is infected with a spam worm.
Unfortunately, there is nothing you can do, but delete these messages and
hope that it ends soon.
You can write a mail rule to move this type mail to the deleted items folder
as soon as it comes in.
