PHP mail keeps hanging

Question

From php.ini

sendmail_path = /usr/sbin/ssmtp -t

The code, which keeps hanging in the browser (I even changed this file to 777)

<?php
error_reporting(E_ALL);
try{
        mail('[email protected]', 'test', 'test');
}Catch(Exception $ex){
        echo 'Exception: ', var_dump($ex, true);
}
echo "Done";
?>

Following works perfectly from terminal

sendmail -v [email protected]
TO: [email protected]
FROM: [email protected]
SUBJECT: test

test
CTRL+D

(Sidenote: I am testing with UFW stopped)

Answer 1

I changed the port from 465 to 587 inside /etc/ssmtp/smtp.conf and it works.

(Good enough for me)
