Mail Setup problems

[theincogtion]

My problem is the mail setup and the documentation:
https://ddvk.github.io/rmfakecloud/install/configuration/#email-settings

Should I set all variables in the docker compose?
And if so which values can RM_SMTP_STARTTLS take?
is it a true or false or just the port number?
I configured it as far as it make sense for me:

      - RM_SMTP_SERVER=mail.your-server.de
      - RM_SMTP_USERNAME=xxx
      - RM_SMTP_PASSWORD=xxx
      - RM_SMTP_FROM=xxx
      - RM_SMTP_STARTTLS=587

Only the ones you need to change,

And if so which values can RM_SMTP_STARTTLS take?

This is only needed if RM_SMTP_NOTLS is set.

is it a true or false or just the port number?

It's a boolean.

Here is the logic that constructs the smtp connection from the options:

rmfakecloud/internal/config/config.go

Lines 193 to 213 in cc67f97

	inSecureTLS, _ := strconv.ParseBool(os.Getenv(envSMTPInsecureTLS))
	noTLS, _ := strconv.ParseBool(os.Getenv(envSMTPNoTLS))
	startTLS, _ := strconv.ParseBool(os.Getenv(envSMTPStartTLS))
	smtpCfg = &email.SMTPConfig{
	Server: servername,
	Username: os.Getenv(envSMTPUsername),
	Password: os.Getenv(envSMTPPassword),
	Helo: os.Getenv(envSMTPHelo),
	NoTLS: noTLS,
	StartTLS: startTLS,
	InsecureTLS: inSecureTLS,
	}
	fromOverride := os.Getenv(envSMTPFrom)
	if fromOverride != "" {
	fromAddress, err := mail.ParseAddress(os.Getenv(envSMTPFrom))
	if err != nil {
	log.Warn(envSMTPFrom, " can't parse address: ", fromAddress, err)
	} else {
	smtpCfg.FromOverride = fromAddress
	}
	}

Here is where the options are defined:

rmfakecloud/internal/config/config.go

Lines 51 to 66 in cc67f97

	// envSMTPServer the mail server
	envSMTPServer = "RM_SMTP_SERVER"
	// envSMTPUsername the username for the mail server
	envSMTPUsername = "RM_SMTP_USERNAME"
	// envSMTPPassword pass
	envSMTPPassword = "RM_SMTP_PASSWORD"
	// envSMTPHelo custom helo
	envSMTPHelo = "RM_SMTP_HELO"
	// no tls, for local smtp mocking etc
	envSMTPNoTLS = "RM_SMTP_NOTLS"
	// use starttls when notls was used
	envSMTPStartTLS = "RM_SMTP_STARTTLS"
	// envSMTPInsecureTLS dont check cert (bad)
	envSMTPInsecureTLS = "RM_SMTP_INSECURE_TLS"
	// envSMTPFrom custom from address
	envSMTPFrom = "RM_SMTP_FROM"

RM_SMTP_STARTTLS is boolean. The the port metioned in the docs is to be used in RM_SMTP_SERVER
In smtp you can start without tls and later upgrade the connection with STARTLS, thats why so many combinations.
the default behavior is to start with TLS for which you need just the address with he correct port
