Mike,
thanks for the documentation update, this makes it a lot clearer what
the "protocol" option actually does. Could you provide a configuration
example? For example, if I have configured my local imap server to
listen on port 8143 (instead of 143), would this be a valid stunnel
configuration?
[imap]
accept = 143
connect = 8143
protocol = imap
Can I enforce starttls? i.e. if the client tries to authenticate to imap
without first issuing starttls, it should be denied and/or the
connection should be terminated.
