SSH tunnel without shell on the remote-host?

Hi,

In order to fetch my emails via POP/IMAP I use an ssh-tunnel to a remote
machine like this:

ssh -L 60000:localhost:143 some.remote.host

This works without problems - however I've got an interactive session on
the remote host that I don't need anyway.

I've tried with

ssh -L 60000:localhost:143 some.remote.host '(/bin/true &)'

but this doesn't seem to work

Is there any way to establish a ssh-tunnel to a remote-host without
having an interactive session?

TIA for your help,
-ewald

According to the man page (you did read it, right?) you can use the -N option. You might want to look at the -f option as well.
