Email error EAUTH 504

Hello everybody,
I have a meteor app in production that returns the following error :

error code : EAUTH
response : 504 5.7.4 Unrecognized authentication type
responseCode : 504
command : AUTH PLAIN

We are using Email.send with smtp on port 25.
The linux server is properly sending email (we have tried telnet port 25 to check).

Do you know if this is an error with meteor/nodemailer or something related to the smtp server ?


Did you config the MAIL_URL environment variable?

Hello yes we did. But apparently the AUTH PLAIN method is not accepted by the smtp server we need to use another authentication method : NTLM, SPA or GSSAPI. Not sure how to do this with Email.send …
