How do I enable TLS/SSL for clients sending mail external to our network?
 
I'm not sure that's what I'm interested in. I want external clients to be able to connect to 465/ssl or 587/tls while they are away from the company/network. Their clients are configured to send email through the proxmox smtp gateway. The gateway needs to authenticate the user against ad/ldap and if they have an account allow the message to proceed.

I didn't see any way to configure such in the web interface so I installed dovecot and configure postfix accordingly. However, there seems to be a process that periodically overwrites my config with what's stored in the web interface's backend db. I'd like to turn this feature off until I can configure it via the web interface.
 
the mail gateway acts as a proxy only, so you cannot authenticate user.

and yes, if you do manual do changes via CLI (e.g. postfix), these settings are overwritten. if you want custom settings you need to modify our "templates", but all these will be overwritten again after uploading a service pack or hotfix.
 
I guess what I'll do then instead is set up an smtpauth server separate from proxmox-mail.
