incoming email from a family member at metrocast.net is blocked before reaching my comcast.net mailbox.

Hey there, @user_26a0c0, thanks for reaching out through Xfinity Forums regarding your email concerns. We would be happy to help with troubleshooting. Are they getting an error message when they attempt to send you the email?

Good morning! Thank you for reaching out! No, no error messages appear. Two reasonably tech-savvy people exchange email twice a day, ordinarily @comcast.net to/from @metrocast.net. Last Saturday (4/18, I think) I did not receive the expected morning email from @metrocast.net. I initiated one myself from @comcast.net that was successfully received @metrocast.net but the reply from was again lost. After some phone chat to consider the possible issues, I sent an email from my @comcast address to @metrocast, cc'd my @gmail address, and asked for a REPLY ALL. My email was received @metrocast and the reply arrived within minutes @gmail; still nothing @comcast - and nothing arrived in a junk folder visible to me. Lost for ideas, I accessed my comcast mail through my browser (login.xfinity.com) and added the @metrocast.net email to my contacts as suggested in one of the forum chains discussing lost email. That has made no difference. I also tried adding my wife's @comcast.net address (along with my @gmail) to the REPLY ALL test. My email reaches her inbox (and @gmail) as expected but the @metrocast.net reply does not reach either of us (except @gmail). I suspect that emails from the @metrocast.net address (or perhaps all metrocast addresses?) is being silently discarded by some spam filter along the path from metrocast to comcast. Any ideas? Thank you in advance.

Hello @user_26a0c0, Thank you so much for sharing the details and for walking through the troubleshooting steps you’ve already tried. We truly appreciate the time you’ve taken. Do you happen to have any spam filters, email rules, or forwarding settings set up on your Xfinity email account that might be blocking or redirecting incoming messages?

No, I have no filters, rules, or other settings that might be blocking incoming email. The problem started last week out of the blue. thx again.

How are you accessing your email? @user_26a0c0
