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.
