Question

This Go program successfully sends email from my home computer, but on a virtual server on DigitalOcean receives the following error:

panic: 530 5.5.1 Authentication Required. Learn more at

Here's the code:

auth := smtp.PlainAuth("", "bjorkbjorksen@gmail.com", "PASSWORD", "smtp.gmail.com")
msg := "Subject: Hello\r\n\r\nWorld!"
e = smtp.SendMail("smtp.gmail.com:587", auth, "bjorkbjorksen@gmail.com", []string{email}, []byte(msg))
if e != nil { panic(e) }

Get to your Gmail account's security settings and set permissions for "Less secure apps" to Enabled. Worked for me.

Derp! I signed into the account and there was a "Suspicious login attempt" warning message at the top of the page. After clicking the warning and authorizing the access, everything works.

You need turn on the POP mail and IMAP mail feature in setting of the email you are using to send mail. Good luck!

in may case setting SMTPAuth to true fixed it. Of-course you need to set permissions for "Less secure apps" to Enabled.

$mail->SMTPAuth = true;
