How Do I Send Email Using Postfix?

The way we to transport emails over the internet is by using a Mail Transfer Agent (MTA) with its Simple Mail Transfer Protocol (SMTP). MAMP PRO uses Postfix as its MTA. Most of the email providers have a strong filter in their systems, which allows to pass only emails with some default headers. The following will help you send email using postfix. You will need to create 3 files, and one new subdirectory.

  1. Add a new host in MAMP PRO, call it “hostmailer”.
  2. Create an “email” subdirectory. Add an empty “InvatationEmail.php”, “invatationMessage.html” and “script.php” to your “email” subdirectory.
  3. In the Postfix tab, check the box “Include Postfix service in GroupStart”.
  4. Set “domain of outgoing emails” to: hostmailer.com .
  5. Save and restart the servers.
  6. Open the hostmailer page and add to the browser path input: hostmailer/email/script.php .
  7. After a few minutes you should receive your email (check if it didn’t go to spam).

Copy and paste the following. This will be your “InvatationEmail.php” file.

  <?php
    class InvitationEmail {
		
		function sendEmailMessage($messageDetails){
			$message_subject = $messageDetails["message_subject"];
			$to_email = $messageDetails["to_email"];
			$from_name = $messageDetails["from_name"];
			$from_email = $messageDetails["from_email"];
			$message_body = $messageDetails["message_body"];
			
			$headers = 'MIME-Version: 1.0' . "\r\n";
			$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
			$headers .= "From: ".$from_name."<".$from_email.">"."\r\n";
			
			mail($to_email, $message_subject,$message_body,$headers);
		}
		
		function generateMessageBody(){
			$myfile = fopen("invitationMessage.html", "r");
			$returnValue = fread($myfile, filesize("invitationMessage.html"));
			fclose($myfile);
			
			return $returnValue;
		}
	}
?>

Copy and paste the following. This will be your “invatationMessage.html” file.

  <!DOCTYPE html>
<html>
<head>
<title>MAMP PRO Invitation</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>

<body>
	Hi there, <br><br>

	You can test MAMP PRO by downloading it from https://www.mamp.info/en/downloads/ .<br><br>

Copy and paste the following. This will be your “script.php” file. Add the correct email address.

 <?php

/*__________________INPUT_DATA______________________*/

    $to_email = "john@gmaill.com"; // you are sending email to .. change the email recipient
    $your_name = "john";

/*____________________SCRIPT________________________*/
    
    require("InvitationEmail.php");
    
    $messageDetails = array();
	$messageDetails["message_subject"] = "Invitation to MAMP PRO";
	$messageDetails["to_email"] = $to_email; 
	$messageDetails["from_name"] = "MAMP PRO";
	$messageDetails["from_email"] = "donotreply";
		
	$invitationEmail = new InvitationEmail();
		
	$messageBody = $invitationEmail->generateMessageBody();
	$emailMessage = str_replace("{name}", $your_name, $messageBody);
		
	$messageDetails["message_body"] = $emailMessage;
		
	$invitationEmail->sendEmailMessage($messageDetails);
	
	$returnValue["status"] = "200";
	$returnValue["message"] = "Email sent to ".$to_email.". Check it in your Inbox or Spam Folder";
	echo json_encode($returnValue);
?>
