Is the email being blocked because of actions by Hotmail and Wanadoo or NTL - the problems seem to have coincided with the introduction of the new SPAM filter on NTL (however I have this configured to off now and emails are still not getting through) and perhaps this is just a coincidence.
I saw in an earlier thread that someone suggested Wanadoo was blocking email to ntlworld - is there anywhere I could find a list of which ISPs won't talk to each other?!
Thanks,

NTL block all email which contains in the header any IP address registered in the SORBS database. This issue has been discussed extensively in other threads, one started by me, but this appears now to have been archived. Basically they just discard "offending" emails without returning any acknowledgement, so it appears to the sender as if NTL could not be located. This has reduced email communications within the committee of which my wife is secretary to a shambles!
I have it from the horse's mouth that NTL have no intention of changing this policy as it is "in the best interest of users". They say it's up to the sender to raise this issue with their ISP. Unfortunately this is at best a blunt instrument, as it could be an intervening relay that is blacklisted, not the sending ISP, and in some cases whether the sender gets through to NTL seems to depend on which part of the country the NTL recipient lives in.
It's nothing to do with the spam filter. However it's worth diisabling this to see how many false positives it would have raised. It seems to get particularly upset about financial emails, even when these are genuine and from reputable sources. Unfortunately it also reveals a steady and disturbing increase in junk email apparently sent bcc to multiple NTL addresses. The latest one I received (bcc) was a "registration confirmation". There is a somewhat heated discussion on this (started by me) here:
