Hmmm. Well, yes, grep tells me that I am. Quite a bit, apparently.
Never noticed. Never looked, either. :)

Understandable, but that does make it more difficult to analyze the problem.

Well, that all depends on what Comcast's definition of
"misconfigured sender" is. For all we know, their idea of a
misconfigured sender is anyone with the name "Paul". :)
Hmmm, wait, nope, your mail doesn't show that way in my Comcast
mailbox. So it's not that. :)
As a wild guess, I'd say Comcast is throwing that in when the name
given in the HELO does not resolve to the IP address of the
sender-SMTP.

Comcast su... err, nevermind.
Seriously, is there a reason you care, beyond "if something's broken
it should be fixed"?
