I don't know if it is related to the above report, but my outbound mail through Comcast's Exchange servers is being blocked by some recipients. 

Please see the rejection notice below.

Hello tgeairn,

Welcome to the forum.

The community would like to help, but could you clarify few items for us?

1. When did this issue started?

2. Have you try to send your email via Webmail?

Thank you

Comcast-

I am getting a  message from one of our e-mail accounts-

omta02.westchester.pa.hmc1.comcast.net.

Bounce back messages exceed email.

I have run Norton a few times but it still continues to not allow sender to send out e-mails. She can recieve just not send.

Thanks,

Rich
