Email Headers are not being generated for my outbound email

[morrisacct]

What gives?  About a month ago, my email suddenly stopped being received by long time recipients.  After no luck with Tech Support 1, 2, and 3 I am not forced to do investigation on my own.  Looking at the "sent" emails, there are no headers being generated.  If I log onto a VPN, which changes my public IP address, no problem.

Any assistance would be appreciated.  Thanks

Are you using webmail, or an email client?

In webmail, when you open a sent mail, click on the three lines and then choose View source.  Are you not seeing headers?

[morrisacct]

Yep.  Using the webmail.  No headers when I view the source.  I've been driving myself batty looking at the differences in the headers when I'm on my work VPN and use the webmail client.  Webmail without VPN starts off with the date field and the last line prior to the body is an X-OS-Marker field which is not in any of the successful emails I can send when connected to my work VPN.  I was thinking it had something to do with how Xfinity is treating my public IP because I get a completely different one on the VPN

This issue has been resolved.  A large block of Comcast addresses were being blocked inadvertantly
