You would think that a company as big as Comcast could run an email server correctly but they can’t. Even simple things that any network engineer knows is beyond their ability to comprhend. And there’s no way to get feedback to the as their support staff is hidden and unresponsive. Which probably explains why they are unaware that they have severe email problem.
So – maybe by posting on my blog the message will eventually get to them and they can fix their problems.
If you are a Comcast customer and wondering why your email isn’t being delivered, it might have to do with the fact that Comcast’s mail servers are severely misconfigured. The main problem they have is that the reverse DNS lookup on their servers have an IP mismatch between what host they say they are and what the host name resolves to. When the server reverse DNS is looked up it returns a name. When the name is looked up it resolves to a different IP. What does the mean? it means the reverse DNS has failed.
So – if you are a Comcast employee or customer or stockholder – or have any Comcast commections – please tell them to FIX THEIR EMAIL SERVERS. I’m getting tired of having to take the blame for Comcast email not reaching my servers.
