dovecot - Dec 2013 - pigeonhole openssl s_client

Hi!

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?


Thanks,
Daniel

Try the gnutls command line interface:

gnutls-cli --starttls --print-cert -p 4190 example.com
STARTTLS
Ctrl-D
LOGOUT

Ah, thanks! Pretty dumb of openssl not to be able to connect arbitrary
servers... in a useful way, that is.
