NGINX- LE for SMTPS, SUBMISSION, IMAPS

[AndyX90]

Hi all,
i would like to use NGINX to Offload Letsencrypt Certificates on my internal services SMTPS, SUBMISSION and IMAPS.
In https://docs.nginx.com/nginx/admin-guide/mail-proxy/mail-proxy/ it is stated that you need to configure nginx with the following arguments: --with-mail --with-mail_ssl_module.
Our nginx plugin is configured with the arguments --with-mail=dynamic and --with-mail_ssl_module.
Is this setup possible with our default nginx plugin?

THX

The plugin does not support mail and the backend code to wrap the nginx authentication protocol is also missing.

I can tell you that pop3s and imaps should work with the current version while smtps does not. I have no idea for SUBMISSION.

Have you thought about the postfix plugin for SMTPS/SUBMISSION offloading?
