My cleint, Renaissance Secondary School (rensec.org) is having a problem whereby emails they send to comcast.net email addresses are not being delivered. I worked on this with Google, and they were not able to resolve the problem because everything on their end is configured properly. I found a forum entry (https://forums.xfinity.com/t5/Email-Web-Browsing/Gsuite-Messages-not-getting-through-to-Comcast-net/td-p/3031238) from another user who had the same issue, and their domain had been flagged as problematic by Comcast. Can you please take a look at my domain to see if we've been similarly flagged?
Thank you in advance for your help.
