First Google a bit, found a lot of questions related to the question but no relevant solutions, in the phpclasses also did not find the relevant classes so they look at the stmp of the relevant agreement to begin to try Curl
SMTP protocol
This can be found on the internet a number of relevant examples, you can experiment with Telnet to connect mail server

PHP Test Code:
Copy Code code as follows:

<?php
Header ("Content-type:text/html;charset=utf-8");
$SMTP = Array (
"url" => "Mailbox SMTP server Address",
"Port" => "Mailbox SMTP Server Port",//General 25
"username" => "username",
"Password" => "password",
"From" => "Send Address",
"To" => "receiving address",
"Subject" => "test the title",
"Body" => "test the content"
);
$CRLF = "\ r \ n";
$test = "";
$curl = Curl_init ();
curl_setopt ($curl, Curlopt_url, $smtp [' URL ']);
curl_setopt ($curl, Curlopt_port, $smtp [' PORT ']);
curl_setopt ($curl, curlopt_timeout,10);
function Inlinecode ($STR) {
$str = Trim ($STR);
return $str? ' =? UTF-8? B? '. Base64_encode ($STR). = ':'';
}
function Buildheader ($headers) {
$ret = ';
foreach ($headers as $k => $v) {
$ret. = $k. ': ' $v. \ n ";
}
return $ret;
}
//
$header = Array (
' Return-path ' => ' < '. $smtp [' from ']. ' > ',
' Date ' =>date (' R '),
' From ' => ' < ', $smtp [' from ']. ' > ',
' Mime-version ' => ' 1.0 ',
' Subject ' =>inlinecode ($smtp [' Subject ']),
' To ' => $smtp [' to '],
' Content-type ' => ' text/html; Charset=utf-8; Format=flowed ',
' Content-transfer-encoding ' => ' base64 '
);
$data = Buildheader ($header). $CRLF. Chunk_split (Base64_encode ($smtp [' body ']);
$content = "EHLO". $smtp [url]. $CRLF; Let's have a hello.
$content. = "AUTH LOGIN". $CRLF. Base64_encode ($smtp ["username"]). $CRLF. Base64_encode ($smtp ["Password"]). $CRLF; Verify Login
$content. = "MAIL from:". $smtp [' from ']. $CRLF; Send Address
$content. = "RCPT to:" $smtp ["to"]. $CRLF; Inbox Address
$content. = "DATA". $CRLF. $data. $CRLF. "." $CRLF; Send content
$content. = "QUIT". $CRLF; Exit
curl_setopt ($curl, Curlopt_returntransfer, true); Curl Receive returned data
curl_setopt ($curl, Curlopt_customrequest, $content);
$test = curl_exec ($curl);
Var_dump ($test);
echo "<br/>\r\n";
Var_dump ($content);
End
Curl_close ($curl);

The above is just a test of PHP
Package test + modification took nearly 6 hours to make the product code compatible with Fsockopen and curl
Later, write an SMTP class that is compatible with Fsockopen and curl simple send mail
