Not necessarily true, given the number of misconfigured Winblows boxes on
cable modems that are frequently used/abused by spammers and crackers.  The
contracts generally prohibit running any kind of servers, but this is
usually ignored unless there's a specific problem with a customer.

Many of the cable providers finally started blocking incoming connections
on port 80 in response to Nimda and Code Red.

We generally set up our customers who're on cable or DSL so that their
mailers send and receive mail through one of our servers using uucp over
TCP, configuring their domains (or subdomains off or ours) so that we're
the primary MX forwarder.  Their mailers don't accept incoming SMTP, and
have all outgoing mail routed through the smart-path to ours.  This
eliminates any problems with their provider's port blockins, and bypasses
the provider's mail system entirely -- a large benefit as anybody who
experienced the wonderful @home mail systems can attest.
