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 ?
