Hello everybody, I'm having a little bit of an issue here, but I'm not entirely sure if this has something to do with Docker...

I'm running a dockerized laravel application inside an AWS EC2 server, but every time I try to call the Mail function, I'm getting this error:

exception: "Swift_TransportException"
file: "/var/www/api/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php"
line: 457
message: "Expected response code 250 but got code "530", with message "530 5.7.1 Authentication required↵""

Everything works perfectly on localhost, using the same dockerized application and running it with docker-compose as in my EC2 ubuntu instance (i'm using mailtrap).

So... Do I need to install or configure something inside my docker container like ssmtp or anything related to php/smtp itself?

FYI .env is configured properly.

Thanks in advance.
