php中通過curl smtp發(fā)送郵件

更新時間：2012年06月05日 23:53:24 作者：

公司的云平臺把fsockopen關(guān)掉了,如果要使用smtp外網(wǎng)的郵箱來發(fā)送郵件的話只能試試使用curl來進(jìn)行了

先google了一下,發(fā)現(xiàn)很多問相關(guān)問題的但沒有相關(guān)的解答,在phpclasses里也沒有找到相關(guān)的類于是自己邊看stmp的相關(guān)協(xié)議邊開始嘗試curl
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 '^]'.

php測試代碼:

復(fù)制代碼代碼如下:

"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']);

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; 
} 
//

$data = buildHeader($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

$content .= "QUIT".$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);
