comcast definately rings a bell, or sorespot :D not as bad as cox, who has
horrible spam policies and no technically inclined people running there mail
setup.
I have checked most of the blacklists and our server IP
(12.184.45.102) does not appear on any of them.
thats a good start but did you specifically check the comcast RBL our just
the public ones? they offer there own and a get out of jail page at
www.comcastsupport.com/rbl
otherwise if there are continued problems then check if you can send thru your
ISP's email server they generally stay off the RBL for a while at a time. a
filter to send through your ISP when its a comcast or when you get a 554 error
works well.
