The Xfinity spam blocker black hole?

[DDenver]

I am having difficulty receiving emails sent to some sites. THey do not get an error from Xfinity indicating an error. Also, the related websites associated with those email returns are not accessible.

I did a traceroute, unable to resolve target system name. 

Note that they GET my emails. I am using Earthlink as my email provider, not having any issues with other's sites. Yes, I did ad the offending site to my email managed list. I did a trace route on earthlink, it is fine. Also I do not get any error messages fro Earthlink. The Xfinity spam blocker black hole?

Thanks D in Denver

So you are using earthlink (not comcast) as your email provider?  The people are receiving your emails but you aren't getting any replies?  Unlikely that it is anything to do with comcast in that case.  If you haven't already, log into earthlink's web email interface and see if the emails are in there, or possibly in a junk folder in there.  If not, then you probably need to reach out to earthlink support.

Didn't even know earthlink was still around....

Sorry so late to respond. Earthlink is stillaround. i like them, when I switch internet providers I still have the same email, etc. On the issue above, I only started having the issue when I switched to Xfinity, which I did because they gave me a grat intro rate comparatively. My issue is only on some websites. They get my email, I don't get a return or any other response (no spam, nothing). I did find on the Xfinity site that they are using a block of IP addresses listed by Spamhaus as 'bad' so that may be what is getting me in trouble with the ending email provider.

Earthlink email stays with Earthlink. It doesnt cross the internet, come to Comcast email servers and say "deliver this". If your issue is on your earthlink email account, then the issue is to be addressed by Earthlink support regardless of what internet connection you are using.

OK, thanks. I was assuming Earthlink wasn't accepting email from Comcast because Comcast may be using IP addresses that some spam filtering websites list as suspect. Too weird. I will contact Earthlink AGAIN and see if i can get them to fix this for me.

I need you to clarify. When you browse to Earthlinks website to check your email - you are not sending email from Comcast to Earthlink. You are sending data, but not an email. When you send email from Earthlink, you are not sending it from Comcast. Its from Earthlink. The connection happens like so: You(Comcast) > Earthlink website(via Comcast sending/receiving data with Earthlink) > Earthlink Email(Earthlink) > Earthlink outbound/inbound server(Earthlink) > Destination(To wherever you sent the email via Earthlink servers).

If it was an issue with a "black hole" in regards to Earthlink, you would not even see the Earthlink home page.
