    • 1 Answer1. In cases like this, you should check with telnet to see which authentication mechanisms are available by the mail server.

    • You should try to use you own Auth mechanism. Create a Login authentication mechanism by copying PlainAuth from the standard library and replace the two instances of PLAIN by LOGIN.. Then use gomail.NewCustomMailer to use your new auth mechanism. If it works I will update Gomail to automatically use the LOGIN mechanism when PLAIN is not available.
