Dovecot 2.3.10 fails to start due to missing dependency

[Jacob Shea]

-- Message 5 - Fourth Response --

Aki,

I ran the command as you requested. Now Dovecot seems to start correctly.

Here is the Pastebin of the Terminal output: https://pastebin.com/rgwzt6Ck

Question 1: Now, having installed Dovecot before (using 2.2.x), I never 
encountered this issue, only in 2.3.10. Was I supposed to do something 
in preparation or setup of Dovecot before starting it?

Question 2: Now that this cert has been generated, how will this cert be 
used for my setup? What I mean is, I have a signed CA cert for my domain 
that I would now configure Dovecot to use. Would my signed CA cert 
replace the cert that was created in /etc/pki/dovecot/private/dovecot.pem?

My apologies for my ignorance.

- Jacob
