[Users] configuring IMAP over SSH tunnel

[Davide Mancusi]

Hello,

My IMAP server cannot be reached from the Internet, but I can ssh into
a front-end machine and reach it from there. Claws Mail claims to
support IMAP over SSH tunnel, and I noticed that the account
configuration window has a "Use command to communicate with server"
option. However, I could not find any documentation about how I should
set up the connection. Can anyone please give me some guidance? What
command should I use?

Thank you in advance.

Cheers,
Davide
