There may be. I'd not use SSH myself since it isn't free for commercial use.
I'd have to buy the server copy of SSH to be able to offer it as a service
that you pay for.
OTOH, there is vppp which is a tunnel that does PPP over TCP with some lite
authentication. That may be adequate where SSH is probably overkill.
And don't forget that while many people are shutting out spammers from dialup
ports at the server end, some (including we) are blocking SMTP on the dialup
itself (except to local servers). We've had several cases of hit-and-run
spammers in the past, but none since that filtering was put in place.
