SMTP Connection Problems in adonis Mail


I have created my first adonis app which was great fun. Unfortunately the Mail config throws me the follwing error even though I have tested the config in another node app with express and emailjs where it is working with the exactly the same config. Is there anything I have to add or change in the adonis config/mail.js? Any help is appreciated!

code: ‘EAUTH’,
response: ‘535 Incorrect authentication data’,
responseCode: 535,
command: ‘AUTH PLAIN’,
status: 500 } ‘Error Code = EAUTH. Error Name: = Error. Error Status: = 500’

And this is my config/mail.js in adonis:

smtp: {
driver: ‘smtp’,
pool: false,
port: 25,
host: ‘’,
secure: false,
auth: {
user: Env.get(‘my@user’),
pass: Env.get(‘myPassword’)
maxConnections: 15,
maxMessages: 100,
rateLimit: 10


Is there any reason that the user name is defined as my@user in the env file?


No, I just did not want to type my credentials. My Mail Server takes an email adress as user credential. I have learned that Adonis Mail is just a Wrapper around nodemail and I remember that nodemail also caused similar problems.


What SMTP server you use? Is it your self-hosted SMTP or something public like Gmail or Mailgun?
I send mails trough Adonis Mail often, and din’t get any errors.

Does your ‘secure’ set right? Many smtp-server require ‘ssl’.


If this is your self-hosted server, did you try to connect to it via Telnet?


Hi deromanenko,
I’m using a hosted server by the German company Hetzner. The funny thing is that the connection is not working with nodemailer (just tested). When I use emailjs with exactly the same config it works like a breeze. So I guess it’s an issue with my mail provider and nodemailer but I have no clue how to find out.


I finally got it: In nodemailer I must add the options:
authMethod: ‘LOGIN’,
requireTLS: true
otherwise my server defaults to authMethod:‘PLAIN’ which didn’t work out in Telnet. Thanks dromanenko for giving me the hint for testing!


I’m use SMTP connection without problem.
SMTP server gmail.
