Using laravel 5.1 .env:

MAIL_DRIVER=smtp 
MAIL_HOST=smtp-relay.gmail.com 
MAIL_PORT=25 
MAIL_USERNAME=username 
MAIL_PASSWORD=password
MAIL_ENCRYPTION=null

Answer 1

There's an error with how you layout the information.

MAIL_USERNAME should go in a new line.

Like this:

MAIL_DRIVER=smtp 
MAIL_HOST=smtp-relay.gmail.com 
MAIL_PORT=25
MAIL_USERNAME=username 
MAIL_PASSWORD=password
MAIL_ENCRYPTION=null
