发送邮箱的php文件

require_once"email.class.php";

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

$smtpserver="smtp.XX.com";//SMTP服务器

$smtpserverport=25;//SMTP服务器端口

$smtpusermail="new2018oh@XX.com";//SMTP服务器的用户邮箱

$smtpemailto=$_POST['toemail'];//发送给谁

$smtpuser="new2018oh";//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="

".$_POST['content']."

";//邮件内容

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

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

$smtp=newsmtp($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"

";

if($state==""){

echo"对不起，邮件发送失败!请检查邮箱填写是否有误。";

echo"点此返回";

exit();

}

echo"恭喜!邮件发送成功!!";

echo"点此返回";

echo"";

?>

最后还有smtp类无法发送邮件解决方法：

偶然发现网站后台自动发送邮件功能不能用了，报这个错误：

Tryingtosmtp.XX.com:25Error:Cannotconnencttorelayhostsmtp.XX.comError:()Error:Cannotsendemailtoweb@daixiaorui.comstate

大概意思是：无法connenct中继主机smtp.XX.com错误：()错误：无法发送电子邮件

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