SMTP協(xié)議
這個在網(wǎng)上可以找到多相關(guān)的例子,可以自己實驗一下使用telNET去連接mail服務(wù)器
復(fù)制代碼 代碼如下:
$ telNET 郵箱SMTP服務(wù)地址 25
Trying 郵箱服務(wù)IP地址...
Connected to 郵箱SMTP服務(wù)地址.
Escape character is '^]'.
exchange郵箱服務(wù)器地址 Microsoft ESMTP MAIL Service ready at Sat, 2 Jun 2012 15:02:12 +0800
EHLO 127.0.0.1
-exchange郵箱服務(wù)器地址 Hello [郵箱服務(wù)IP地址]
-SIZE
-PIPELINING
-DSN
-ENHANCEDSTATUSCODES
-X-ANONYMOUSTLS
-AUTH NTLM LOGIN
-X-EXPS GSSAPI NTLM
-8BITMIME
-BINARYMIME
-CHUNKING
-XEXCH50
XRDST
AUTH LOGIN
VXNlcm5hbWU6
用戶名(base64_encode)
UGFzc3dvcmQ6
密碼(base64_encode)
2.7.0 Authentication successful
MAIL FROM:發(fā)件箱地址
2.1.0 Sender OK
RCPT TO:收件箱地址
2.1.5 Recipient OK
DATA
Start mail input; end with <CRLF>.<CRLF>
要發(fā)送的內(nèi)容(這里的相關(guān)的規(guī)范有很多)
.
2.6.0 <0b476f30-3b96-4e3d-84d2-395a96d34000@exchange郵箱服務(wù)器地址> Queued mail for delivery
QUIT
2.0.0 Service closing transmission channel
Connection closed by foreign host.
php測試代碼:
復(fù)制代碼 代碼如下:
<?php
header("content-type:text/html;charset=utf-8");
$smtp = array(
"url" => "郵箱SMTP服務(wù)器地址",
"port" => "郵箱SMTP服務(wù)器端口", // 一般為25
"username" => "用戶名",
"password" => "密碼",
"from" => "發(fā)件地址",
"to" => "收件地址",
"subject" => "測試一下標(biāo)題",
"body" => "測試一下內(nèi)容"
);
$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; // 先得hello一下
$content .= "AUTH LOGIN".$CRLF.base64_encode($smtp["username"]).$CRLF.base64_encode($smtp["password"]).$CRLF; // 驗證登陸
$content .= "MAIL FROM:".$smtp["from"].$CRLF; // 發(fā)件地址
$content .= "RCPT TO:".$smtp["to"].$CRLF; // 收件地址
$content .= "DATA".$CRLF.$data.$CRLF.".".$CRLF; // 發(fā)送內(nèi)容
$content .= "QUIT".$CRLF; // 退出
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); // curl接收返回數(shù)據(jù)
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $content);
$test = curl_exec($curl);
var_dump($test);
echo "<br/>/r/n";
var_dump($content);
// 結(jié)束
curl_close($curl);
以上只是測試的php
包測試+修改花了近6個小時讓產(chǎn)品的代碼兼容了fsockopen和curl
以后有空寫個兼容fsockopen和curl簡單發(fā)送郵件的smtp類
php技術(shù)：php中通過curl smtp發(fā)送郵件，轉(zhuǎn)載需保留來源！
