Apparently some malware cracked my email account and has been sending out spam messages with heading like, How are you, or something similar, with a ad message at the bottom.

I have changed my comcast password and it seems to have stopped.

This was revealed to me by a huge number of mail daemon undelivered messages in my inbox. Most of those were to old contacts that have somehow accumulated in my contacts folder over the years. I can only assume that many were received as sent by me.

Goddamned Interweb, sorry about that.
