It snuck through my work's (a University) SPAM filter (SpamAssassin) this morning. It was addressed to
info@obama.com and BC to me (and a huge list of others I'm sure). I only see a couple a month. The last information I saw was from 2006 when there was a peak of 900,000 email messages in one day of which only 50,000 passed the SPAM filter (and there were not many false positives)!! A shocking waste of bandwidth.
My work email address is easily captured from the University's website.
