Bitwarden Self Hosted - OAuth2 & SMTP

Per their documentation, it appears that they only support SSL for encrypted traffic. I would like to avoid the situation where we are sending unencrypted email. Is it possible for Bitwarden to send email via encrypted TLS on port 587 instead of SSL on port 465?

I found another thread where there seems to be some confusion on this as well here: How to set self-hosted bitwarden to use TLS for mail - Ask the Bitwarden Community - Bitwarden Community Forums

Thank you!
