php smtp socket 发邮件

用socket发邮件,socket发送邮件是指上就是通过客户端向邮件服务器发送以上的命令，从而实现SMTP协议来达到发送邮件的目的,但是于邮件服务器交互的时候,不是一下子就结束了,是一条指令,一条指令的发,返回的结果如果是正常 比如 220,250,334,才能继续向下

看这个东西都是网上看的别人的资料,收集了一些觉得别人说的不错的,另外还有一个RFC文档,将smtp,和扩展的MIME头,将的是非常的详细了.(虽然很多我都看不懂)  
[stmp协议介绍 算找到的资料中最详细的了][stmp_]

**一些状态码(不是 http 状态码)**

*  500 格式错误，命令不可识别（此错误也包括命令行过长）
 *  501 参数格式错误
 *  502 命令不可实现
 *  503 错误的命令序列
 *  504 命令参数不可实现
 *  211 系统状态或系统帮助响应
 *  214 帮助信息
 *  220 服务就绪
 *  221 服务关闭传输信道
 *  421 服务未就绪，关闭传输信道（当必须关闭时，此应答可以作为对任何命令的响应）
 *  250 要求的邮件操作完成
 *  251 用户非本地，将转发向
 *  450 要求的邮件操作未完成，邮箱不可用（例如，邮箱忙）
 *  550 要求的邮件操作未完成，邮箱不可用（例如，邮箱未找到，或不可访问）
 *  451 放弃要求的操作；处理过程中出错
 *  551 用户非本地，请尝试
 *  452 系统存储不足，要求的操作未执行
 *  552 过量的存储分配，要求的操作未执行
 *  553 邮箱名不可用，要求的操作未执行（例如邮箱格式错误）
 *  354 开始邮件输入，以.结束
 *  554 操作失败
 *  535 用户验证失败
 *  235 用户验证成功
 *  334 等待用户输入验证信息

每次客户端想服务器发一个指令过服务器便会返回相应的相应信息，信息格式为（响应码+空格+解释）  
一些常见的相应码为：

**简单的过程**  
　　1. 建立TCP 连接。  
　　2. 客户端发送HELO命令以标识发件人自己的身份，然后客户端发送MAIL命令；服务器端正希望以OK作为响应，表明准备接收。  
　　3. 客户端发送RCPT命令，以标识该电子邮件的计划接收人，可以有多个RCPT行；服务器端则表示是否愿意为收件人接收邮件。  
　　4. 协商结束，发送邮件，用命令DATA发送。  
　　5. 以“.”号表示结束输入内容一起发送出去，结束此次发送，用QUIT命令退出。

**客户端向邮件服务器发送的 常用指令**  
HELO hostname 与服务器打招呼并且告知服务器客户端使用的机器名，这里可以随便填写；  
AUTH LOGIN:user,pass 邮箱帐号，密码  
MAIL FROM:sender 告诉邮件服务器发信人的地址；  
RCPT TO:receiver 告诉邮件服务器收信人的地址；  
DATA 开始发送邮件内容，并且最后只能含有"."为结尾字符的行结束。  
QUIT 传输结束，退出连接；

一个简单的例子

<?php
    	class aMail{
    		public static $smtp_prot = 25;
    		public static $debug = true;
    		public static $crlf  = "\r\n";
    		var $smtp_host;
    		var $login_name;
    		var $password;
    		var $form;
    		var $to;
    		var $err;
    		var $message;
    		var $socket;
    		function __construct($options=""){
    			if($options == "" || !is_array($options)){
    				return false;
    			}
    			foreach($options as $key=>$val){
    				$this->$key = $val;
    			}
    		}
    
    		function sendMail(){						 
    			$this->socket = fsockopen($this->smtp_host,self::$smtp_prot);
    			$socket = $this->socket;
    			$crlf   = self::$crlf;
    			stream_set_blocking($socket,true);
    			$this->message = fgets($socket,512);	
    			echo $this->message;
    			if(!$this->print_messsage("/^220/","connect fail")){
    				return false;
    			}
    
    			fputs($socket,"EHLO 127.0.0.1 ".$crlf);
    			$this->message = fgets($socket, 512);				
    			if(!$this->print_messsage("/^2/","EHLO fail")){
    				return false;
    			}
    			
    			fputs($socket,"AUTH LOGIN".$crlf);
    			$this->message = fgets($socket, 512);				
    			$this->print_messsage("/^2/","AUTH LOGIN fail");
    			
    			fputs($socket,base64_encode($this->login_name).$crlf);
    			$this->message = fgets($socket, 512);				
    			$this->print_messsage("/^2/","login_name fail");
    			
    			fputs($socket,base64_encode($this->password).$crlf);
    			$this->message = fgets($socket, 512);				
    			$this->print_messsage("/^2/","password fail");			
    
    			fputs($socket,"MAIL FROM: <".$this->from.">".$crlf);
    			$this->message = fgets($socket, 512);
    			$this->print_messsage("/^2/","from fail");
    
    			fputs($socket,"RCPT TO: <".$this->to.">".$crlf);
    			$this->message = fgets($socket, 512);
    			$this->print_messsage("/^334|^2/","to fail");
    			
    			fputs($socket,"DATA".$crlf);
    			$this->message = fgets($socket, 512);
    			$this->print_messsage("/^334|^2/","DATA fail");			
    
    			$html = implode("",array(
    						"To: ".$this->to.$crlf,
    						"From: ".$this->from.$crlf,
    						"Subject: ".$this->subject.$crlf.$crlf,
    						$this->content.$crlf.".".$crlf,
    					));
    
    			fputs($socket,$html);
    			$this->message = fgets($socket, 512);
    			$this->print_messsage("/^2/","html fail");
    			
    			fputs($socket, "QUIT".$crlf);
    			$this->message=fgets($socket,512);
    			$this->print_messsage("/^2/","QUIT fail");
    		}
    		function print_messsage($reg="",$err=""){
    			$message = $this->message;
    			if(preg_match($reg,$message)<=0){
    				$this->err = $err."___".$message."--------------";
    				echo $err."___".$message."--------------<br>";
    				return false;
    			}
    			if(self::$debug){
    				echo $this->message."<br>";
    			}
    			return true;
    		}
    	}
    	$mail_options = array(
    					"smtp_host"=>"smtp.sina.com.cn",
    					"login_name"=>"ycwtt0527",
    					"password"=>"XXXXX",//填写真实的密码的密码
    					"from"=>"ycwtt0527@sina.com",
    					"to"=>"ycwtt0527@sina.com",
    					"subject"=>"hengheng",
    					"content"=>"<div style='color:#f00'>asfsadfasdf</div><span>haha</span>",
    
    				);
    	
    	$x = new aMail($mail_options);
    	$x->sendMail();
    ?>

运行上面  在页面上会打印

220 irja2-171.sinamail.sina.com.cn ESMTP 220 irja2-171.sinamail.sina.com.cn ESMTP  
250-irja2-171.sinamail.sina.com.cn  
250-8BITMIME  
250-SIZE 73400320  
250-AUTH PLAIN LOGIN  
250 AUTH=PLAIN LOGIN  
334 VXNlcm5hbWU6  
334 UGFzc3dvcmQ6  
235 \#2.0.0 OK Authenticated  
250 sender ok

看到sender ok  算是发送成功了, 但是对方是否能收的到就不一定了........

发送的内容是<div style='color:\#f00'>asfsadfasdf</div><span>haha</span>

发现在收邮件的时候这个标签被转义了,(如果发的是图片,我试了几次都收不到)

这是就要靠MIME扩展来解决这个问题了

大概看了2天相关的内容,结果完全晕了....

MIME的扩展 真心看不大懂   然后看了下phpmailer  就更晕了  光 content-type就有8bit ,7bit ,text/plain,iso-8859-1,base64

然后发邮件又有个中参数  附件 图片 多媒体   等等  n多分枝(因为要根据设置了不同的参数来设置MIME头,在phpmailer里面有create\_header,create\_body 2个方法,对这边有比较多的判断,我是没兴趣看了)

想看  MIME部分 还是 去看 RFC文档  配合 phpmailer一起看可能效果好点

算了  放弃了     用phpmailer 发了封简单的邮件

看  怎么拼简单的html邮件

如下

To: ycwtt0527@sina.com  
From: <ycwtt0527@sina.com>  
Subject: hengheng<br>  
Return-Path: ycwtt0527@sina.com  
MIME-Version: 1.0  
Content-Transfer-Encoding: 8bit  
Content-Type: text/html; charset = "iso-8859-1"

<div>asdasdasdasdasdasd</div>
