I turned off the Comcast Brightmail filter because they had too many false 
positives and offered no way to white list these senders.  They requested I 
send these emails to them (Comcast) as Mime attachments with headers intact 
but 3 weeks after forwarding dozens of examples, they had not whitelisted 
any of the emails.  Most are newsletters I subscribe to but some were just 
personal emails.  One was from my sister with just the sentence "I agree, 
Bro :)" as the body!!!

Brightmail seems to be particularly blind to text emails offering phony 
degrees despite the constant phone number they could key on.  Also, they 
don't filter on dynamic IP ranges from the big broadband providers.

Based on their advertising, Brightmail relies solely on spamtrap mailboxes 
so they are also blind to spammers who obtain your address with methods that 
Brightmail doesn't use to attract emails and to any spammers who might be 
smart enough to avoid the Brightmail traps.

All in all, they claim 95% accuracy and 0% false positives.  I'd say they 
get 60-75% of the spams and maybe 5% of the non-spam is being blocked by 
them.

Be sure your ISP allows you to check the blocked emails and you check them 
often to determine whether wanted emails are being blocked.
