Letsencrypt.org has one other thing you should know about, not a biggie, the certificate is only good for 90 days at a time. Then you need to renew. But they though about that too, you can automate the renewal, so that each time the certificate expires and new one is generated and installed. It is supported by all of the major browsers, by supported, they are a part of the group that funds letsencrypt.org

certbot works only with ports 80 or 443? Can lego work with with IMAP ports like 143 or 993? The documentation is not very clear.
basically - independent of the client - letsencrypt will only support http/https or dns based challenges.
so - if you want to get certificates for an imap only server, you will have to setup an webserver for the challenge. or deal with your dns server.
