Thanks to Leonardo and Michael,

I have made some progress. The snaps application is not supported by 
RedHat/CentOS. The solution is simple,? just use:

# yum install certbot

The new error message is this:

# certbot certonly --apache

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Could not choose appropriate plugin: The requested apache plugin does 
not appear to be installed
The requested apache plugin does not appear to be installed

I am trying to find which is the "requested apache plugin". The log 
mentions "authenticator".

I am hoping that an Apache Certificate will be useful for Dovecot.

just wondering: Do you have an apache webserver running on this machine?
If not, run

# certbot certonly --standalone

or read https://certbot.eff.org/docs/using.html

and don't forget to open port 80 in your firewall. letsencrypt wants to
access that port.
