Bitwarden On-Prem: SSL Error when connecting to SMTP Server

We use a Lets Encrypt cert on our mail server in the cloud. Unfortunately, this causes a small problem - the Bitwarden On-Prem is unable to verify the SSL certificate, which means it can’t actually send emails.

Does anyone have a solution for making Bitwarden’s API backend recognize the LetsEncrypt certificate for the email server?

Did you get solution for this?

Not within Bitwarden, no.

Ultimately, I spun up a separate Postfix relay instance without SSL enabled that delivers to the proper mail server we use, and from there it works as expected. However, I found no Bitwarden-specific solutoin for this, the way I worked around this was a ‘dirty hack’ workaround.
