Thanks, Joh

Assuming OUTSIDEBOX can connect to your
OUTSIDEMAILSERVER, you should be able to connect

using

the tunnel in #1, then another tunnel:

2a) ssh OutsideboxUser@localhost -L
9993:OUTSIDEMAILSERVER:993 -p 2022

Then point your email client at localhost:9993

You can forward anything TCP. You just need to 'chain
them along'. For example:

ssh OutsideboxUser@localhost -L 9993:OUTSIDEMAIL:993
-L 3389:OUTSIDELDAP:389 -L 2000:OUTSIDESIEVE:2000 -p
2022

Then use your client to:
ldap localhost (port 3389)
sieve localhost (port 2000)

etc..
