## FAQ

### x509: certificate signed by unknown authority

If you get this error it means the certificate used by the SMTP server is not
considered valid by the client running Gomail. As a quick workaround you can
bypass the verification of the server's certificate chain and host name by using
`SetTLSConfig`:

    mailer := gomail.NewMailer("smtp.example.com", "user", "123456", 587, gomail.SetTLSConfig(&tls.Config{InsecureSkipVerify: true}))

Note, however, that this is insecure and should not be used in production.

### 504 5.7.4 Unrecognized authentication type

If you get this error, you should try using the LOGIN authentication mechanism:

    addr := "smtp.example.com:587"
    auth := gomail.LoginAuth("username", "password", "smtp.example.com")
    mailer := gomail.NewCustomMailer(addr, auth)
