Comcast email is not receiving emails from some user addresses in the same domain but is from others

[wsf01]

I cannot receive emails from some address of a certain domain, however I can recieve them from others in the same domain.  I have two email accounts with comcast and the same emails will not go through on either. I do not not recieve any spam alerts from these unreceived emails, nor do they go to my junk/spam box.  I primarily use Outlook as my viewer, however they do not show up on the Xfinity viewer either.

@wsf01  please PM me the email addresses you are having issues with

The specific email address that is not going through is:  grandvilleadmin@elitefitnessgroup.com

One that is coming through is: Kristen.Bova@elitefitnessgroup.com

Thanks!

grandvilleadmin@elitefitnessgroup.com - has only sent email to our server once in the last 30 days and it was a successful to inbox delivery. I also reviewed the domain as a whole and it appears there WAS filtration, but it was cleared up by 3/24 by the domain owner. 

Can you confirm that from elitefitnessgroup.com someone specifically stated that an email would be coming from the admin of their domain to your inbox and confirmed the email to be sent? or are you expecting emails from admin but instead are getting them from a user within the group? 

Regardless, if im seeing successful deliveries from admin to the inbox, but you state that you never got an email from them... then you may want to have their IT take a look at the SMTP log of when they sent you the email to see what may have happened. Comcast is not blocking the domain and is no longer filtering them either.

Thank you for your assistance.  It appears it was on the senders end!  

On a similar issue, a subsidiary of this group uses a different domain for their specific communication and I am not recieving those emails as well.  Again they have not gone to spam nor to the junk folder in either viewer.  I confirmed they are sending the emails to the correct address and asked they also send to another address on my comcast account - neither were received, they did not get a notice of failed sends.

I sent them your reply and asked they look into it on their end, but if its not too much to ask would you please verify that the following domain is not blocked either: admin@grandvillefbbc.com

Thank you!

that one specifically is being blocked because people who receive their emails in a majority of cases hit "this is spam". Looks like about half their traffic is being filtered at this point. They will want to audit their mail listings because of this and potentially sign up for the Comcast Feedback Loop.

otherwise they will likely end up being filtered again because our users are reporting them as spam. I've processed a clear of the filtration, but if it continues they will end up right back on it in 15 minutes. The clear should go through in approximately an hour.

I'll inform them - thank you very much - your support was awesome!
