Hi,

Can anyone confirm my suspicion that some NTL server and/or netblock IP addresses have been listed in blacklists somewhere?

I am, at present, unable to send e-mail to aol.com addresses and others like knujon.com.

Typical NTL server bounces are:
Nov 21 11:44:06 router postfix/smtp[52284]: 02DC5102F61: to=<contact@knujon.com>, relay=smtpin.ntlworld.com[81.103.221.10]:25, delay=2.3, delays=0.03/0.06/2.1/0.11, dsn=5.0.0, status=bounced (host smtpin.ntlworld.com[81.103.221.10] said: 550 relaying mail to knujon.com is not allowed (in reply to end of DATA command))

This bounce was solicited by my server which is hosted on a NTL broadband connection. It's been working perfectly until recently.

Regards,
Neil Darlow
