[Dovecot] pigeonhole openssl s_client

I'm trying to get information about a server certificate from a
pigeonhole sieve server.
Various connection attempts show only "wrong version number" or "unknown
protocol" errors from openssl:

$ openssl s_client -connect example.com:4190 { -tls1, -tls1_1, -tls1_2 } [ -starttls { imap, pop3 } ]

None of these work. I'm trying to see who signed the server cert. How
could I do this?
