Emails not being delivered?

I did try that and they do go through. Emails from Xfinity come through as well.

If you send yourself a test message from some other email provider you have like Yahoo or Gmail, does it go through OK?

I'm having the same problem, I haven't changed any of my settings at all but I'm not getting emails that I should have.  A few minutes ago a forum I'm on told me my address was no longer considered vaild as no emails were going through.  This is most annoying.

EDIT:  Tried sending from a Gmail account and it got through.  But stuff from Spacebattles ( the forum I'm on ) and other stuff doesn't seem to be getting through at all

That being the case, call Comcast security and see if there is a blocking issue for the sender's domain-------------------

Mail server not responding

Thanks, I'll pass that response on to the mods there as well.

I did speak with 2 people this morning. Currently have gotten 2 email outside of xfinity. The resynced the account. Hopefully that's all it needs.

@math227 The server shows all emails being sent to you as delivered in the last 14 days. If you are not getting emails you are expecting, it would be an issue on the sending side, not the receiving side. 

How on earth can this happen for days and days?  If they are doing major changes, let us know and we can use alternatives.  This is awful.  I suspect the problem is a very successful phish attack on COMCAST that happened last week.   They could avoid this if they would communicate with users like everyone used to do 10 years ago - phone or snail mail.   If everything is email, anybody can make it look like something came from them and they wanted me to update password.   Welcome to the virtual world. 

On my end I found out that the forum I wasn't getting messages from hasn't been able to deliver any emails to comcast.net addresses and is trying to work out why they're being blocked.  Live chatted with an agent and shared the details I was told with her, said she was gonna have someone look into it so hopefully that will clear up.

Not sure that'll help other folks having issues with emails getting blocked.

I found out what happened.  Someone stole my password (Phish?) and got into my account and sent a bunch of emails.  How this can happen from an unknown IP is beyond me (Comcast Security?).  All of the incoming emails were then filtered by said user for fun I guess - assume not someone in Comcast - to go into TRASH folder, hence no mail to be delivered to my Outlook or mobile email app.   I fixed filter and back to normal.
