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:

d := gomail.NewPlainDialer("smtp.example.com", "user", "123456", 587)
d.TLSConfig = &tls.Config{InsecureSkipVerify: true}

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