Good thing I use Gmail.

I'm having the exact same problem, but with Hotmail (MSN) rather than Yahoo Mail. My account was apparently hijacked at some point, so it's sending out those commercial messages also. VERY annoying!!! So I've just tried your method Carmine, and deleted all my contacts, to see if it will work in Hotmail as well. I sure hope so because I don't want to have to cancel my Hotmail account if I don't have to. I guess all I can do is wait and see. It's too bad we can't get ourselves deleted from other peoples' contact lists. . .

There's some excellent advice here, so thanks Richard! I am still waiting to see if Carmine's suggestion of deleting my Contact List will solve my hijacked email site problem -- and so far I can report that my email hasn't sent out any bogus emails since then, but I've received a few from a couple of people who were on my now-deleted Contacts List. Meanwhile, getting back to the suggestions in this posting, I have also now added a cell phone number to my profile, to be used by Microsoft to notify me if my account is hijacked, and can also be used as an alternate password in case I'm locked out (by hijackers or otherwise). Microsoft also suggests we add an alternate email for the same purpose, but I don't want to take a chance that a hijacker could access that information also. I've also started "logging off" or "signing out" every time I exit my email. It's kind of a pain, but I think it may reduce a 3rd party's access to it. And it just occurred to me today, that frequent deleting of all cookies in my system might help as well. What do you think?
