smtp发送邮箱个人觉得比php mail函数要实用的多了,mail函数不是随便可以发邮箱的需要进行相关配置哦,下面我们来看一个关于smtp类发送邮箱与问题解决方法。

当你还在纠结php内置的mail()函数不能发送邮件时,那么你现在很幸运,此时的这篇文章可以帮助到你!

php利用smtp类来发邮件真是屡试不爽,我用过很久了,基本上没出过问题。本博客后台,当博主回复留言时候,会自动给网友发一封有新回复提示的邮件也是用的本文这个方法实现的。

smtp类发送邮件的方法其实很简单,也很稳定,类是别人已经写好的了,你只需要调用就行了。几行简单的配置就能发邮件,是不是很期待的试一试呢!

发送邮箱的php文件

 代码如下 复制代码

<?php

 require_once "email.class.php";

 //******************** 配置信息 ********************************

 $smtpserver = "smtp.126.com";//SMTP服务器

 $smtpserverport =25;//SMTP服务器端口

 $smtpusermail = "new2008oh@126.com";//SMTP服务器的用户邮箱

 $smtpemailto = $_POST['toemail'];//发送给谁

 $smtpuser = "new2008oh";//SMTP服务器的用户帐号

 $smtppass = "您的邮箱密码";//SMTP服务器的用户密码

 $mailtitle = $_POST['title'];//邮件主题

 $mailcontent = "<h1>".$_POST['content']."</h1>";//邮件内容

 $mailtype = "HTML";//邮件格式(HTML/TXT),TXT为文本邮件

 //************************ 配置信息 ****************************

 $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//这里面的一个true是表示使用身份验证,否则不使用身份验证.

 $smtp->debug = false;//是否显示发送的调试信息

 $state = $smtp->sendmail($smtpemailto, $smtpusermail, $mailtitle, $mailcontent, $mailtype);


 echo "<div style='width:300px; margin:36px auto;'>";

 if($state==""){

  echo "对不起,邮件发送失败!请检查邮箱填写是否有误。";

  echo "<a href='index.html'>点此返回</a>";

  exit();

 }

 echo "恭喜!邮件发送成功!!";

 echo "<a href='index.html'>点此返回</a>";

 echo "</div>";

?>

效果截图欣赏:

 


填写收件人,标题和内容后提交

 

 

返回成功的提示


瞬间便接收到了邮件

 

smtp类无法发送邮件解决方法


偶然发现我网站后台自动发送邮件功能不能用了,报这个错误:

Trying to smtp.126.com:25 Error: Cannot connenct to relay host smtp.126.com Error: () Error: Cannot send email to web@daixiaorui.com state


大概意思是:无法connenct中继主机smtp.126.com 错误:()错误:无法发送电子邮件给web@daixiaorui.com

上网找了n多资料后终于找到了解决方案,不是smtp类的问题,而就是linux配置的问题。原来是服务器的php.ini 禁用了fsockopen函数。


打开空间下的php.ini文件,linux空间一般都可以自定义php.ini,所以根目录下面一般会有这个文件。


有两个地方可能禁用此函数:

1. allow_url_fopen = On 查看等于后面是否为 ON,如果为OFF时函数将被禁用

2. disable_functions = fsockopen pfsockopen (我的就是这样)这里应该去掉前面的“fsockopen”。使之变成:disable_functions = pfsockopen


改过之后,保存,再重新刷新页面,就发现在linux下能成功利用smtp类发送电子邮件了。感谢网友分享的方法,问题终于得到了解决。
