SSL Error

[Brandon Roa]

Oops, on second glance I don't think that error is actually directly 
related to what I was doing.

I had been testing to see if the certificate chain was installed 
properly by running

openssl s_client -connect mail.example.com:143

But there was no certificate reported in stdout. I thought that error 
was related to my test command, but I realize now it's not. I'm still 
confused, though, because I followed all the steps for installing 
configuring SSL (https://wiki.dovecot.org/SSL/DovecotConfiguration) and 
it just doesn't seem to have worked.
