Hi, I'm using Mailpit in a container. While trying to send an email with authentication, I receive the error "Authentication credentials invalid" with any combination of login and password.

Could you please provide an example of the correct environment variables or the proper format to specify the login and password? Also, are there any extra variables I should set?

I want to use PLAIN authentication with SMTP.(force_ensecure=True)
