Hi James,
I agree the solution I proposed is probably a much better fit for
different email problems. The principal one being email privacy concerns
in certain settings. Furthermore, after researching further, I found
that almost all of the SSH clients available for mobile devices are
designed as PTY console devices, with port forwarding (if included)
being only an ancillary feature.
However, for anyone who DOES want an email-specific private tunneling
solution, I found one Android app that I consider a perfect fit. I
haven't discovered a similar app for IOS devices. (Although there are a
couple of good SSH apps available for remote console) The app I found,
which is called "SPT", for "SSH Persistent Tunnels", isn't free (as in
beer) but its price won't break anyone's bank. (Available on Google's
app store)
I am personally installing the app on all my Android devices. This
extremely lightweight app ONLY does background SSH port forwarding. No
console included. Another factor in its favor is it doesn't require
rooting. The "persistent" in the name comes from the intent of its
designer: It "...tries to maintain ssh tunnels over the frequent change
of network and disconnects typical for a mobile device. SPT tries to
reconnect each time a new network comes up." Reviewers indicate it does
exactly that. You can basically send and receive totally private emails
continuously while being highly mobile.
