Testing imap over ssl seems a little more difficult:

[root@snapper downloads]# telnet finninday.net 993
Trying 24.21.185.50...
Connected to finninday.net.
Escape character is '^]'.

I'm not sure how to construct a transaction by hand, but when I quit, I got this in the log:

May 15 10:43:46 weasel imapd-ssl: Unexpected SSL connection shutdown.
May 15 10:44:50 weasel imapd-ssl: couriertls: accept: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

So I'm getting past the firewall and talking to the imapd-ssl process.

This might be helpful information:

rday@weasel:~$ couriertls -host=finninday.net -port=993
couriertls: connect: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
