Laravel 6 send mail

I have an issue with authentication while sending mail with Laravel smtp driver.

.env file:


It gives the following error:

"530-5.7.0 Authentication Required. "

  • 2-Factor auth is enabled and app password is used;

  • Also tried with SSL on 465, same error;

  • Config is flushed every time .env is changed;

  • Everything in config/mail corresponds to .env;

SO all typical solutions are not working. What else may cause this problem?

I have also tried using with vivaldi account, it authenticates, but gives an error:

"no valid recipients"

while recipient email is surely valid, which is also strange for me.

I've stumbled across this multiple times already, hence I do not remember the exact error-message which I received but here is my assumption.

Google has an option called "less secure apps" which you need to enable in order to send directly mails through their SMTP interface. Can you check if this flag is disabled and try to enable it?

In addition to that google is slowly deprecating this feature. Starting from Mid 2020 you'll be not able to enable this flag anymore and they will completely remove this in 2021.
