Are you doing a straight delivery to port 25 from your Mail Client?

I was, now am doing an alternate port, with exactly the same
restrictions.

IOW

Evolution local machine --> 
	Port 25 on uno.gregfolkert.net --> 
	regular scheduled delivery

Now its
Evolution local machine --> 
	Alternate Port on uno.gregfolkert.net --> 
	regular scheduled delivery

Because Comcast say they are being anti-spam proactive.

Whatever.
