Inviting Team Members - Email Configuration Issue?

[badmonky]

Trying to add a team member in postiz says "invitation email sent"

The env file has EMAIL_PROVIDER="nodemailer" set.

However In the logs i see the following error:

Are there any other configurations we have to take to make this work?

Turns out to be a configuration issue of the email on the domain I am using. May be a good thing to mention in the postiz docs to double check those.

Still unsure what the expected behavior is now that the email goes out. It does not seem to add the user after they click the link. But that may be a postiz issue, not on cloudrons side.

If anyone has similar issues. How i got around it was by adding a user to cloudron, and ask them to use the "Login with [cloudron instance name]".
