Re: NTL emails don't fare too well with Spampal
Freeserve marks a lot of legitimate newsletters and advertising mails as spam - content evaluation, unless you can accurately hunt down the anti-bayesian crap that spammers seem to use - perhaps by looking for FONT-SIZE: 0px or other typical "invisible text" markers, is just too risky - all advertising, wanted or not, will come up as "spammy".

DNSBL blacklisting of:
1. Already known proxies
2. Direct to MX mail from dynamic (formerly dialup) user space (DUL)
is a far better solution - ISP's could field a lot of junk that way - I'm 100% in favour of DUL blacklisting at the server level.
