Answer 1

Try SMTP to send the mail from Another server->

$mail = new PHPMailer();
$mail->IsSMTP();
$mail->CharSet = 'UTF-8';

$mail->Host       = "mail.example.com"; // SMTP server example
$mail->SMTPDebug  = 0;                     // enables SMTP debug information (for testing)
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->Port       = 25;                    // set the SMTP port for the GMAIL server
$mail->Username   = "username"; // SMTP account username example
$mail->Password   = "password";        // SMTP account password example

There can be at least these two approaches.

1. Using mailer server as SMTP

• Install and configure an SMTP software like Postfix on the system you want to make mail server

• Then in the webserver use a library like PHPMailer of SwiftMailer to send email using the mailserver's ip address and created smtp user.

2. Using mail sererver's PHP mail()

This is the other way around.

• Access the database installed in the webserver in the mailserver machine by using the webserver's ip address as the hostname and the respective username and password.

• You will need to enable remote connection to the database. If its mysql then you can see the following question: Remote Connections Mysql Ubuntu
