emails to me returned as undeliverable
In the past week I've received messages from two financial institutions that emails to me ...@comcast.net have been returned as undeliverable. Why is this happening for only these specific senders?

Hello @user_6423da Thanks for reaching out to us here on Xfinity Forums. When the issue is with very specific senders, but you still receive other emails then there are a few things you can check and try.
Check Your Filters & Blocked Senders List – Sometimes, an email filter or block list can accidentally prevent certain emails from reaching you. You can check this by signing into your Xfinity email, going to Settings > Email Filters & Blocked Senders, and making sure their email isn’t blocked.
Check Third-Party Email Apps (If Applicable) – If you’re using an email app like Outlook or Apple Mail, make sure their emails aren’t getting filtered or caught in a junk folder there.
Whitelist Their Email – You can add their email address to your contacts and create a filter to always deliver their messages to your inbox. In Xfinity email, go to Settings > Filter Rules, create a new rule, and set it to always send emails from their address to your inbox.
Try a Test Email – Have them send a plain text email (without attachments or links) from a different email address, if possible, to see if it's an issue with their domain or just their specific email.
If none of those solve the issue you will want to reach out to our Customer Security Assurance at 1-888-565-4329 or submit a ticket with them at https://spa.xfinity.com/report
