I couldn't use tcpconnect (my "own" server isn't really mine and
tcpconnect isn't installed).
This configuration worked for me:
UseIMAPS no
RequireSSL no
Tunnel "ssh my-server openssl s_client -connect
my-mail-provider:993 -CApath .ssl -quiet"
The downside is, now the imap traffic isn't encrypted between
my-server and my-mail-provider.
What I'v done instead is this:
Port 10993
UseIMAPS yes
CertificateFile certfile
And then:
ssh -L 10993:my-mail-provider:993 my-server sleep 20 &
sleep 5 && mbsync ID
The trick here is: "sleep 5" causes mbsync to wait until the tunnel is opened.
"sleep 20" is executed on "my" server and keeps the tunnel open until mbsync
takes use of the tunnel. Once mbsync finishes the tunnel closes by itself.
Thanks for the help.
Niko.
