A recent example is "Error 421". Maybe the answer is to move from NTL!!

Whilst it's a nice conspiracy theory, the truth is much more prosaic - if no less frustrating. NTL ignore all email which has originated from, or passed through, a host registered on either of two databases of hosts known to relay "spam". One is SORBS. ISPs can get their hosts removed from the SORBS database, but they will reappear if more spam appears.
Recently Yahoo! has been intermittently blacklisted, which is a pain for many of us who are registered with Yahoo! forums - and in at least one case a forum moderator!
But why should NTL "Play god"? I still get masses of spam (80% of which is intercepted by NTL). So there are two issues. First, that there is no way that NTL can prevent spam (any more than anybody else can). Second, they have filters in place which can trap most of it in any case. So why ruin the email service for thousands of people, by reducing it to little more than a lottery? What if somebody sends me something urgent, and NTL decide that because it "could be spam", they will just ignore it? And now many other such emails have NTL thrown away which I am unaware of?
