But now, it looks like a lot of the problems with spam and Hotmail are due to a new vulnerability in the Hotmail service that allows spammers to script their spam sending.
[COLOR=royalblue]"Hotmail has always been a problematic spam source. The saving grace has been that the spam had to be transmitted manually, through a web form, so the sending rate was limited by how fast the spammer could cut-n-paste. Now that Microsoft has provided this new programmatic interface for spammers, that limit has been removed. Spammers may now script their spam runs--and they do--which has created a huge increase in spam transmitted by Hotmail. Out of my last 25 Hotmail spams, 2 were transmitted by web form and the rest by the DAV exploit: a 2200% increase!"[/COLOR]
