[hpsdr] Comcast.net Delivery Problems Again

[Don AE5K]

For the dozen or so subscribers to this list who have a comcast.net address:

We now have definite documentation of what is happening to your email
from our HPSDR Discussion List and it is just as suspected: Comcast has
blacklisted the IP address used by our list email server. (again!)

Here's an example "bounce" message received late this evening (I used
Eric's since his email address is widely known on this list):

> Final-Recipient: rfc822; ecellison at comcast.net

Many of you will NOT get this email directly (since it will be blocked),
but I hope you will read it in the archive to know what is happening.
Tomorrow (Monday) when I get time, I'm going to try an experiment to see
if we can get around this problem and will let those affected know if it
works out.  No guarantees!
