Hi i am trying to send emails in laravel.But when trying to send it is genrating following error and mails are not sending. But everything worked fine in localhost without any problems.

  Failed to authenticate on SMTP server with username "[email protected]" using 2 possible authenticators. Authenticator LOGIN returned Expected response code 235 but got code "535", with message "535 Incorrect authentication data
     ". Authenticator PLAIN returned Expected response code 235 but got code "535", with message "535 Incorrect authentication data"

MAIL_PORT=465
[email protected]
MAIL_PASSWORD=MyEmailPassword
MAIL_ENCRYPTION=ssl
[email protected]
MAIL_FROM_NAME='LifeLoveAndOtherThings'

I havent added additonal code in config/mail.php

'stream' => [
    'ssl' => [
        'verify_peer' => false,
        'verify_peer_name' => false,
        'allow_self_signed' => true,
    ],
],

I havent changed or added my emails in config/mail.php.I have set it up only in .env file. What is the issue here.

Answer 1

I have a similar error and I enquoted my password and it worked like charm.

MAIL_PASSWORD="YourEmailPassword"

If the problem still continues try using username, password and port number in double quotes.

If you are using your personal Gmail account then follow these steps :

1. Go to https://myaccount.google.com/security#connectedapps
2. Take a look at Security menu -> Apps with account access menu.
3. You must turn the option "Allow less secure apps" ON.

If you have already followed these steps, try re-starting your project. and if it still doesn't work, please continue these steps :

1. Visit https://accounts.google.com/UnlockCaptcha
2. Click continue button

Good luck!

Answer 2

For me, this was my problem

Authenticator XOAUTH2 returned Expected response code 235 but got code "535", with message "535 5.7.3 Authentication unsuccessful 

This happened suddenly after a few month in production (before it worked perfectly). After having visited other post with similar question, none of which worked, the solution that I found was...

to change the password and WAIT SOME TIME in order to be effective.

I know, I know

I think that the password on outlook was expired after some time. The config was the same.
