Please name at least 5 *personal* webmail providers that features
enhanced spam filtering via Brightmail Anti Spam technology. Price is
not an issue and other features are desirable but not essential. The
provider must sell directly to individuals i.e. they're dealing in
single webmail accounts.

I'm not interested in:
1. Having my own domain name
2. Having multiple webmail accounts

A good example would be http://www.netaddress.com

They seem to only work with ISPs. Free email provider BigFoot used to
use them, but not now.

I've a usa.net work webmail account which uses Brightmail Anti Spam
technology. From my personal experience, Brightmail yielded not a
single false positive for over 7 years and Brightmail eliminated 99%
of spam!

I've broadband at home so I'm not interested in signing up with
another ISP. I'm sure there are stand alone webmail providers that
offer Brightmail Anti Spam technology. Any other spam filtering
technology is simply useless.
