In this Post i show How to solve Swift_TransportException (530) : Expected response code 250 but got code 530 with message 530 5.7.1 Authentication required Error in Laravel.
When you Got this error :
When you trigger to send Mails with misconfigured Mailables and then this error occured.
How to Fix this Error :
Check your Mailable Configuration values.
I use mailtrap.io for testing emails in local Environment.
Register and login your account in mailtrap.io and goto demo inbox settings.
Get your mailable configuration Credentials
Just need to edit your .env file like below:
MAIL_DRIVER=smtp MAIL_HOST=smtp.mailtrap.io MAIL_PORT=2525 MAIL_USERNAME=********** MAIL_PASSWORD=********** MAIL_ENCRYPTION=null
After modify your settings in .env you need to run following commands
php artisan config:clear
php artisan cache:clear
Restart your server
sudo service apache2 restart
Try to clear your browsers cache & cookies and try again Hope that works
Note : if you using Gmail account as SMTP you must turn on less secure app settings in your Gmail account here https://myaccount.google.com/lesssecureapps
