I'm on the other side of this one.  I run on a dynamic IP cable modem, and
smarthost all my outgoing email through my ISP's smtp server.  Forget about
perceived privacy problems for a moment - it's in the contract.  I could buy
a static IP from them and route out directly; currently, they BLOCK outgoing
port 25 traffic past their network for dynamic IPs.

I wish more ISPs would do this.  In fact, I specifically wish Comcast would
do this.  I block each and every Comcast connection I can from their dynamic
blocks, because they DON'T do this.  Why?  Because at one point I was
getting hit with over 1000 attempts per day to deliver spam and viruses from
dynamic IPs on Comcast's network, and Comcast didn't do a damn thing about
it.  Still, I get quite a few hits; because of the blocks they go right in
the bitbucket.  I have no illusion about "privacy" rights when I'm using
someone else's private property for my transmission, even under contract.
And they'd be fools to permit unmonitored communication over their network.
