Comcast is screwing its customers by blocking “spam” which isn’t spam and also preventing mail servers which are accused of “spamming” from being removed from Comcast’s blacklist. I’ve tried to respond to two support requests from Comcast subscribers recently and in both cases, my reply bounced.
I got this back rom my mail server:
Reporting-MTA: dns; ********* Final-Recipient: rfc822;********@comcast.net Action: failed Status: 5.0.0 (permanent failure) Diagnostic-Code: smtp; 5.4.7 - Delivery expired (message too old) 554-'IMTA06.emeryville.ca.mail.comcast.net comcast ***.***.***.*** Comcast BL004 Blocked for spam. Please see http://help.comcast.net/content/faq/BL004' (delivery attempts: 0)
(Of course “***” are places where I’ve removed identifying information).
On following the link to http://help.comcast.net/content/faq/BL004, I get a page which suggests I can go to http://www.comcastsupport.com/rbl to get my mailserver unblocked. However, following that link redirects me to http://www.comcastsupport.com/browserupgrade/ which gives me a 404 Not Found.
Way to go, Comcast.
Update 25/8/2010: Seems like this has been fixed.
