公司的云平台把fsockopen关掉了,如果要使用smtp外网的邮箱来发送邮件的话 只能试试使用curl来进行了
先google了一下,发现很多问相关问题的但没有相关的解答,在phpclasses里也没有找到相关的类于是自己边看stmp的相关协议边开始尝试curl
SMTP协议
这个在网上可以找到多相关的例子,可以自己实验一下使用telnet去连接mail服务器

php测试代码:
1 <?php 2 header("content-type:text/html;charset=utf-8"); 3 $smtp = array( 4 "url" => "邮箱SMTP服务器地址", 5 "port" => "邮箱SMTP服务器端口", // 一般为25 6 "username" => "用户名", 7 "password" => "密码", 8 "from" => "发件地址", 9 "to" => "收件地址",10 "subject" => "测试一下标题",11 "body" => "测试一下内容"12 );13 14 $CRLF = "\r\n";15 $test = "";16 $curl = curl_init();17 18 curl_setopt($curl, CURLOPT_URL, $smtp['url']);19 curl_setopt($curl, CURLOPT_PORT, $smtp['port']);20 curl_setopt($curl, CURLOPT_TIMEOUT,10);21 22 function inlineCode($str){23 $str = trim($str);24 return $str?'=?UTF-8?B?'.base64_encode($str).'?= ':'';25 }26 27 function buildHeader($headers){28 $ret = '';29 foreach($headers as $k=>$v){30 $ret.=$k.': '.$v."\n";31 }32 return $ret;33 }34 35 // 36 $header = array(37 'Return-path'=>'<'.$smtp['from'].'>',38 'Date'=>date('r'),39 'From'=> '<'.$smtp['from'].'>',40 'MIME-Version'=>'1.0',41 'Subject'=>inlineCode($smtp['subject']),42 'To'=>$smtp['to'],43 'Content-Type'=>'text/html; charset=UTF-8; format=flowed',44 'Content-Transfer-Encoding'=>'base64'45 );46 $data = buildHeader($header).$CRLF.chunk_split(base64_encode($smtp['body']));47 48 49 $content = "EHLO ".$smtp["url"].$CRLF; // 先得hello一下50 $content .= "AUTH LOGIN".$CRLF.base64_encode($smtp["username"]).$CRLF.base64_encode($smtp["password"]).$CRLF; // 验证登陆51 $content .= "MAIL FROM:".$smtp["from"].$CRLF; // 发件地址52 $content .= "RCPT TO:".$smtp["to"].$CRLF; // 收件地址53 $content .= "DATA".$CRLF.$data.$CRLF.".".$CRLF; // 发送内容54 $content .= "QUIT".$CRLF; // 退出55 56 curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); // curl接收返回数据57 curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $content);58 $test = curl_exec($curl);59 var_dump($test);60 echo "<br/>\r\n";61 var_dump($content);62 63 // 结束64 curl_close($curl);以上只是测试的php
包测试+修改花了近6个小时让产品的代码兼容了fsockopen和curl
以后有空写个兼容fsockopen和curl简单发送邮件的smtp类
