One possible hurdle is the fact that your source domain will probably
*not* be the ISP's domain, so your routing your domain email outbound
via their servers would require special MTA rules on their part
(except for the subcase where you're trying to send mail to another
user at that ISP).

Think "open relay". The ISP mailserver should only be accepting mail
*from* their domain or *to* their domain. Mail from and to domains
they don't own should be blocked.

You might have problems getting them to permit relay by a domain you
own if you don't have a business-class account (and thus a higher
level of support).
