I found the following scripts useful when using Zimbra and Let's Encrypt

https://github.com/yetopen/certbot-zimbraJust thought some might appreciate it, although a reverse proxy is much better.
I thought they had it built-in now? Need to upgrade my home lab, but don't know when I'll get around to it.

It has not been, it has been always manual...

I setup a reverse proxy in front and no issue so far. Version 8.8.11 on Zimbra.

On the same box, or on a different box?

Different Box.

Because the issue is, the cert gets issued to the reverse proxy server. So you need a process to grab it from there.

For me, the Reverse proxy handles everything, that is the Zimbra server never sees that Certificate ever.

Ah ha. That's VERY different than our process.

Including IMAP and SMTP traffic?

As we talked on the private chat, not IMAP and certainly not SMPT as SMPT is not over TLS.

Since acquiring and renewing a certificate can be automated with Certbot, would it make sense to have the cert in two places? HTTP/HTTPS traffic passes through your ngingX VM, which receives its certificate through its own instance of Certbot. And you have a second instance of certbot that functions on the Zimbra server itself, so you have a cert for IMAP and SMTP connections.
Or, for you, does it not matter that IMAP and SMTP connections are unencrypted? Since beyond your own mail server, there's no guarantee that encrypted connections will exist.

We do both over TLS.

You could, but it would still be such a pain to automate as certbot can't renew the certs alone for Zimbra, that you might as well just use one.
