Email messages not being received by comcast customers

I'm having a similar issues.  When I send emails through my comcast account, they say they are sent - but the receiver never receives them.  I also tried sending myself an email through my comcast account, and I cannot receive it.  How do I fix this?

I have an Office 365 account and I do not recieve emails that are sent to my xfinity email.  I will recieve them if I turn off the spam filter.  How can I fix this?

@6778700 This should be resolved shortly.

@Peters92 I need to know a bit more information.  Could you gather the headers from one of your test messages and send it to me in a PM? (I can help you do that via PM if you don't know how)

Hello @6778700, thanks for visiting our Forums! I do see it was stated that this issue should be resolved shortly but I wanted to confirm, has this issue been resolved on your end? 

Hello @gcmo, thanks for reaching out to our Forums! At this time, I am not showing this reported as a known issue reported to our national board. I would be more than happy to assist you with this email concern. Can you please send me a private message including the full name as it appears on the account and your full name if different?

To send me a Private Message, please click my name “ComcastAmira” and click “send a message". 

As of about 11:00 am 5/11/19 my wife and I have stopped recieving most emails, and I've checked using both POP and web access.  The spam folder contains nothing either.  I sent two test emails this morning 5/12/19 which originated from two different web servers that I own on two different domains.  One made it through and the other did not, yet the missing one does not show up in spam.   Similarly, a personal test email sent from different domains shows that some domains get through and others do not.  My guess is that this is an overactive spam filter somewhere at the server level since I've had that happen before.  I hope the missing emails are being stored somewhere, since we have missing receipts for services we purchased.  Is this issue being looked at by comcast still?

Yes, thank you, it is resolved after two days.  Clearly this is the better forum to get a response since my phone call apparently went nowhere.  This is the third time I've had emails collected by some ghost software filter on the comcast side without any notification.  Presumably it's an overactive spam or domain filter that has been innappropriately configured?  Now I turn off my individual spam filter because that's the only way I'm sure I'm actually recieving all my important email.  As long as I have a constant stream of garbage coming in at least I know I'm getting everything.     

@johnpainter So, the strange thing is that for about 48 hours, I didn't see any messages coming in for you at all.  Not that we were flagging them as spam, they just weren't there.  And then there was a large burst and now it looks normal again.

Well, obviously I have no inside knowledge of your systems.  What I do know is that after I stopped getting emails I did a test from two domains that I own, from web reply forms on remote servers and also from pop email I use that goes through a third party DNS service out of Canada.  One of the domains was allowed through and I got the email within a minute or two, the other one did not get through and I only got the email days later when this whole thing was fixed.  Emails from other well known domains, including facebook, also failed to get through.  As you saw, they were stuck somewhere outside of the comcast user mailbox.  In the past I've seen this with anti-spam or other protective software on the DNS level which sets up white/black lists using behavioral algorithms or third party lists.  If that is the underlying problem I don't know where but in comcast-land the software would  be installed and configured, unless a a third party is screening emails for comcast.

@jodylewis This should now be resolved.

As a side note, I'd recommend that you verify that your spam folder is enabled, and spam messages are being delivered to the Junk/Spam folder.  It seems like you currently have that option disabled.

My issue was resolved too.  

Thank you.

@ComcastAntiSpam  I actually just turned that feature off earlier this week to see if it would help the problem.  FYI, even when it was turned on, nothing went into that folder....it was always empty.  So???
