Re: Mail sent from @comcast.net address failing to delivery

Thanks for the help. I did get put through to a helpful tech, who could tell that it's the destination mail server which is rejecting email from Comcast mail servers. He contacted the support resources at the destination and opened a ticket with them to remove the block, but as of midnight last night I hadn't heard anything new and destination seems to still be blocking. Will follow up again today, and will post an update here for others benefit.

 

Cheers,

Worth a try! The only specific advice I can think of is "be persistent". CSA has access to email server logs and such so they should certainly be able to help you out. If the response you get doesn't answer your question, keep at them.

 

If you get a chance, please post your results. Good luck!

Thanks BruceW, will give that number a call. Any tips/tricks on getting past the first-line reps? Does the code word "fizzbin" work? Smiley Wink

Comcast Security Assurance should be able to help you with this, if you can get past the first-line reps. Call them at 1-888-565-4329 (from http://constantguard.comcast.net/dedicated-support/contacts#s5_nav).

Mail sent from @comcast.net address failing to delivery

I am unable to email from my comcast.net account to a specific email recipient, but testing from my gmail account to the same recipient is successful.

 

The error information returned to my comcast.net account is:

 

      This is an automatically generated Delivery Status Notification.      

Delivery to the following recipients was aborted after 1 second(s):

  * <----- email recipient address ----->

where "<----- email address removed ----->" is the recipient I am unable to contact from my comcast.net address.

 

Is email from Comcast.net being blocked specifically by the recipient's email server? Or has Comcast.net ended up on a blacklist that the recipient's email server uses?

 

What action can I take to resolve this as quickly as possible?
