Can't enable TSL/SSL Authentication on Poste.io

This affects me also.
The @githubsaturn and @laruche method 1. did not work.
I also tried the @locvfx method of
adding into configs the 3 additions of; Path in App - path on host details. After this the mail server would not restart.
re: Caprover will tell you to change nginx config : DONT FOLLOW
-how does one revert these changes? I probably did follow the instructions!

ps emails are sending for me in my desktop client, Kmail, but I cannot send invoices from Invoice Ninja and this seems to be the problem.

Let me know if you find a solution!

@coffseducation to revert the nginx changes you can simply delete everything in that textarea, caprover will then re-apply the default configuration.

Still haven't found a solution to enable TLS

Apologies I failed to respond. Thanks for the info.
Closed? Did you get this sorted or give up?
I tried all of the advice in combinations but still could not get it working.

Posteo.io has these settings

I copied the keys from the directory:
/captain/data/letencrypt/etc/live/YOUR-APP-NAME/privkey.pem etc
I then pasted them into a new file and uploaded.
I not sure what file goes to each upload so I tried a mix.
Still not working.

How is iRedmail? It looks to set ssl also, so I assume the same issue.
I suppose Caprover is really not setup to host an email server. It would seem be to go with a dedicated hosting service.
