[TowerTalk] Attn all comcast subscribers

[Richard (Rick) Karlquist]

Comcast did not block this port until last month.
Then, without announcing it, they started blocking
it.  I wasted a couple of hours trying to figure
out why I couldn't send mail all of a sudden.

Of course my ISP provides an alternate port.
