We have an SMTP server set up that I would like to use. Currently, we are requiring StartTLS to access it through the internet. When I attempt to configure Auth0 SMTP Server, the test emails fail due to a self-signed certificate. Can the certificate be changed to a cert from a known authority?
I was able to reproduce this. It doesn’t make sense to me, I think many SMTP servers use self signed certs.
You should be able to work around this by installing a fully signed cert in your SMTP server.
I’ll report back if I find anything interesting out.
