[TASK] Sending an Email with ESMTP Protocol

Postby admin » Tue Oct 17, 2017 10:28 am

We will go through an example of sending an Email by PHPoC Blue or Black.

There are two popular protocols to send Email: SMTP and ESMTP.
PHPoC supports libraries for both prototol. Depending on your mail server, you might use SMTP or ESMTP protocol. For example, Gmail uses ESMTP, so, to send email from a Gmail account, you need to use ESMTP library.

This example is a simple course uses the ESMTP library to send email from Gmail.
For sending email using SMTP protocol, refer to this example

Source Codes
1. task0.php
Code: Select all


// avoid php execution via http request

include_once "/lib/sn_dns.php";

"PHPoC example : send email via out-going mail server\r\n";

//esmtp_setup(udp_id, tcp_id, "x.x.x.x");
//esmtp_msa("smtp.naver.com", 465);
//esmtp_msa("smtp.daum.net", 465);

$subject "msa test";
$message "Hi PHPoC\r\nThis is PHPoC msa test email\r\nGood bye\r\n";

$msg esmtp_send("to_id@to_domain.com""to_name"$subject$message);

$msg == "221")
"send mail successful\r\n";
"send mail failed\r\n";
