Answer 1

i had the same issue long time but i have fixed it

While you are in the local serve ie) xampp or wampp etc

MAIL_DRIVER=smtp


MAIL_HOST=smtp.gmail.com
MAIL_PORT=465
[email protected]
MAIL_PASSWORD=password
MAIL_ENCRYPTION=ssl

but when you are going in live server

MAIL_DRIVER=sendmail


MAIL_HOST=smtp.gmail.com
MAIL_PORT=465
[email protected]
MAIL_PASSWORD=password
MAIL_ENCRYPTION=ssl

Just Change the mail driver to sendmail I have no idea how its is working but it fixed my server-error-503
