Are you quite certain it's a "someone" and not a "something"? You
*could* be infected with the Klez worm:
"The virus e-mails itself from infected machines using a bogus "From"
address randomly plucked from all e-mail addresses stored on an

Klez Worm, Not Sender, Hates You
Though the worm was at its peak last Spring, it hasn't been thoroughly
eradicated and still pops up quite commonly. Those infected often
complain of exactly what you're experiencing.
To see if you have Klez (and to get rid of it), go here:
Download and run SpyBot Search and Destroy, Patrick Kolla's nifty
utility to get rid of Trojans, Hijackers and Spyware from any Windows
machine. If you are infected with Klez, SpyBot S&D will find it and
get rid of it (and, happily, any other assorted nasties you have

First, turn on Full Headers in your e-mail client. If you don't know
how to do this, just tell me what you're using for e-mail (Outlook

Next, register for a free spam reporting/header reading account at
Julian Haight's SpamCop:
You can use this service to report spam and have abuse reports filed
on your behalf, or just to trace headers to send your own abuse
notifications. Basic spam reporting/header tracing is free.
All signed up? Full headers on? Good. Copy and paste the full

and you'll be shown a line by line breakdown of where the e-mail has
come from, concluding with an abuse address.
You won't be given the sender's identity, but you will be given his
ISP's abuse department, to which you can forward a copy of the
offending e-mail (with full headers) and request that they discipline
their user. (They won't give you his identity without a court order -
the privacy clauses in most Terms of Service prohibit the sharing of
such information - but they will usually cut off his account.)
For a quick visual explanation of how to read e-mail headers, have a
look at the great visual explanation given by MaximumPC magazine in
January of this year:

I hope you find this helpful! If anything is unclear or you need help
either getting your full headers to display or would like help reading
the headers yourself, please don't hesitate to ask for clarification.
I'll be glad to assist you.
