Is there a way to disable built-in Let's Encrypt?

[Greg]

I'm currently exploring how to pass in my own certificate, but another question that I can't seem to find the answer for is how to disable Poste's attempts to generate a Let's Encrypt certificate on its own?

You should leave it at poste - it handles reloading dovecot, haraka, nginx with new cert automaticaly. If you want to use something like jrcs/letsencrypt-nginx-proxy-companion there is example setup https://gist.githubusercontent.com/analogic/51fbe91b580d7913b72320f89bf994cc/raw/7dc4f4d413f5d3de314558de9c987fb022d6df1a/docker-compose.yml (there is no problem to issue multiple certs for one domain at LE)

Yeah but what if Let's Encrypt turns evil or something better comes along? The ability to pass in your own certificate would be very useful in such a case. Plus, I have a container that I've setup for handling all my Let's Encrypt certificates and renewing them. I don't want to have Let's Encrypt stuff split across multiple containers, and I don't want to use someone else's setup.

@analogic - Will using Poste in this way — by supplying my own certificates as described here — cause any problems with Poste and its Let's Encrypt stuff?

That's what I'm mainly concerned about — I don't want my supplying of certificates to come into conflict with Poste's Let's Encrypt system.
