Yes, similar story in my case, my domain, mcgregor.org
from time to time got hundreds of spam bounce messages
per day... SPF can help the situation but doesn't
solve it totally. 

Bottom line, for a spammer to forge an e-mail address
is beyond trivial, and while you can slow them down on
that score you will never stop them...

My next issue (and it is a small one) in this area is
dealing with user education... I have mcgregor.org,
but there are other mcgregor domains. So I sometimes
get e-mail that were clearly intended for a fertilizer
company in Washington, a Baptist church in Florida,
and very occasionally a retirement home in Ohio
(mcgregoramasa.org). Does anyone have suggestions on
how to reply to such wrongly addressed e-mails that is
memorable, yet inoffensive...
