[Evolution] Re: imaps over a firewall

[Mike Godfrey <migod uwaterloo ca>]

So pardon me for being stupid, but I feel like I'm almost there ... and
need just a bit more help.

I am using "connect" from http://www.imasy.or.jp/~gotoh/ssh/connect.html
so my .ssh/config file looks a bit like this (names changed etc etc):

        Host external.server.net
                ProxyCommand connect -H local.proxy.net:8080 %h %p

(the external server runs both the sshd and imaps).

If I run this:
        ssh -L 5143:external.server.net:993 external.server.net
then I get a normal telnet-like ssh connection.  Is this what I want? 
Is this connection secretly doing port redirection while I read news,
use vi, etc?

If I tell evolution to connect to localhost:5143, evolution says that
the local host is refusing connections to port 5143 (I am a newbie at
this port/networking stuff).

Any hints/advice greatly appreciated.
