How can Comcast Support for Email (CSA) be contacted privately, regarding an email delivery issue from a particular email sender?

@XfinityCSAEmail 

Hello Comcast Support for Email,

Thanks for the quick response. So, since around October 2021, certain email from Wells Fargo bank are not successfully being delivered though to my  [Edited: "Personal Information"]  email inbox coming through my personal domain email address of  [Edited: "Personal Information"]  which are forwarded through from my Domain Name Host provider at Pair Networks (pair.com), and I want to double-check that they are not being blocked on Comcast.net email server's side. (My Comcast.net email Advanced Setting's Spam Filtering is set to: Override Security Filters. And no Filter Rules are being applied.)

I've spoken with Technical Support at Wells Fargo and they indicate that they can discern that those certain emails are indeed being sent, but are then bouncing back. Please verify that Comcast.net email servers are not blocking / filtering these inbound email addresses:

I've also written Pair Networks Tech Support, and they figure that Comcast's email servers might be blocking email traffic coming from their email server's domains/IP addresses. Please verify that these are not being blocked / filtered: 

virulha.pair.com  (209.68.5.166)  

mailwash38.pair.com  (66.39.2.38). 

So, I'm writing to ask if Comcast Support can correct/override/fix anything on your end, so that Wells Fargo bank email being sent to my  [Edited: "Personal Information"]  email address which is then forwarded from Pair Networks can come through to my  [Edited: "Personal Information"]  account again? 

Everything had been working fine up until late-September / early-October 2021, in this configuration. No changes have been made to any configurations within my Comcast Email webmail's settings, nor my Apple Mail desktop email client's software. My [Edited: "Personal Information"]  email address' inbox/outbox work normally, otherwise. So, I know it's not on my receiving software's end; it might be deeper within the Comcast email server level(?).

Hopefully this info is sufficient to be able to lift any Blacklist being applied to certain Wells Fargo emails sent to my  [Edited: "Personal Information"]  emails coming through Pair Network's email service, and then forwarded to my account at Comcast.

Thanks,

Nick [Edited: "Personal Information"]

Good morning,

In regards to Wells Fargo directly to you - it appears half the emails are being delivered while the other half are failing DMARC record checks. Similarly for Pair with a much smaller margin of error. The logs show that there are some being marked as spam, which is not a hard block, just a filtration to the spam folder. It doesn't show any specific blocks placed on the sender/domain outside of well... server configuration issue(s) from the sending side in regards to their DMARC records. More information on DMARC can be found here: https://postmaster.comcast.net/dmarcupdate.html 

Overall, looks like both Wells Fargo and Pair need to look over their DMARC records for any errors that is causing these issues. 

Hey there. What do you mean by emails that go to more than 5 addresses are being delivered? You are receiving spam emails?
