Thank you!

Ok, so I can omit ssl=no and startssl=no, and this results in default settings for ssl which is 'off'? Or the defaults are 'on' anyway?

Can I somehow specify ports on remote hosts that proxy will use to connect to? Like (just image): 'proxy host_imap=10.1.1.1:143 host_pop=10.1.1.1:110' or somehow?

Due to certain design issues, the ssl=no is actually same as ssl=yes, same goes for starttls=no. So there is no support actually for "ssl=no" at this moment.
