Nice try though... Best protection is through your email client. O2K3 does
it native ^^


I realize that, my point was that blocking more is better than blocking 
less.  Whenever you can block everything and allow only the needed 
traffic, you'll be better off.  Removing as many possible 'phone home 
vectors' as possible certainly can't hurt and is good security policy in 
general.

Why don't you guys just cut to the root of the problem and not use
mail clients that access files on other people's servers when you read
your mail.  HTML e-mail sucks.
