I use a combination of Spampal (particularly the excellent regex filter), The Bat (far safer and more feature rich than Outlook or Outlook Express) and Zone Alarm Pro (blocks unsafe attachments and prevents mass emailing). I've no problems. I do get loads of spam but most of it (approx 98%) is flagged and moved to a common spam folder (i.e. all spam sent to all my accounts is shifted to one folder, and deleted from the server so my inboxes don't become full).
I have an account "mapspart@ntlworld.com" that I give out on newsgroups and other dodgy places. Emails sent to this address are given 200 points by Spampal.
It never ceases to amaze me that despite people knowing how bad NTL is at providing services (including customer services), they still want NTL to filter out spam
You really think NTL will manage to do it effectively? You really think you won't lose important emails? How will you know if you've lost an email if the sender doesn't phone/write to say emails are being bounced (assuming they are bounced and don't just "vanish")?? You scream for spam protection because you can't/won't implement your own, and when NTL provide spam protection you'll scream because they're making a mess of it
I've posted about this before on a similar thread - virus protection yes, spam protection no. Shouldn't even need virus protection if people installed their own firewall and virus scanner
It's been suggested that NTL might maintain a blacklist, but like I said before - if NTL's customers have trouble contacting NTL and getting them to do stuff, what hope will the owners of blacklisted servers have?

Pretty much runs itself. Like said - spam is automatically removed from the server; all other emails are left until they're deleted by NTL.
