Warning: serious geekery here. I’m posting this for my own future reference.
if you’re behind a firewall but want to use a service from the world wide web…. ssh to the rescue! Or is it ssh is the curse of IS admins? Well it is their own fault for thinking that blocking port X outbound is going to stop me from using service Y on port Z.
SSH TUNNEL
If you can connect to the remote server using SSH, then we can setup
a secure tunnell through SSH for your POP communications. The tunnell connects
a port on your local machine ( say 1234 ) to the POP3 port ( port 110 )
of your remote server.
$ ssh -P -f -L 1234:remoteserver:110 user@remoteserver sleep 25
