I try to send an email from my METEOR server as described: https://docs.meteor.com/api/email.html
But i want to send emails without authentication. I have no username and password. If i try MAIL_URL=smtp://@relay.xy.xxxxx.com:578 without username and password i get the error:
unable to verify the first certificate.
Is it possible to set a parameter like “SMTPAuth=false” as in PHP?
