Spam slime from Hotmail? Hotmail addresses were frequently forged in
spams, but very little spam actually comes from Hotmail. Nonetheless,
Hotmail is good about cancelling accounts used as dropboxes for spams.
The trend in these forgeries has been away from Hotmail, AOL and other
companies that take an agressive stance and more towards smaller ISP's
which may lack the will or resources to agressively pursue the spammers.

Yes, this is a good idea since there probably always will be abusers or
rogue domains out there.
