下面是我找到的一个直接使用smtp发送邮件的php例子程序(经改编), 但是服务器方总是提示: 550 system busy! 并且邮件无法发送.
那位知道如何处理?
另: 对于smtp服务器需要密码的情况该如何处理验证呢?
sory , 刚刚看到 smtp 发送邮件的问题 (链接的这个帖子怎么不是精华?, 建议斑竹给一个啊).
问题已经解决:
1. 命令data应该是”data\r\n”
2. from和to命令应该有, 否则一些server拒发邮件
3.使用base64_encode 加密用户名和密码
<?php
require(“php\mail.php”);
?>
<?
$smtp = “smtp.163.net”;
$from =”hylpro@163.net”;
$to = “hylpro@163.net”;
$subject =”hello php mail”;
$message=”hello! this is a test use php”;
$mail = new mail($smtp,”welcom use this mail”,true);
$mail->send( $to,$from,$subject,$message);
?>
