很难过,博主的博客一直无法使用邮件回复功能
甚至是用户注册都没有办法
使用了各种插件,各种代码依然无果
也问了好多人,他们怎么不知道告诉我阿里云禁用了25端口?
如果你看到了这个帖子,你离成功不远了,哈哈

方法一:改用使用smtp 的ssl协议使用465端口来发送邮件

<!--?php /** * 邮件发送类 * 支持发送纯文本邮件和HTML格式的邮件,可以多收件人,多抄送,多秘密抄送,带附件(单个或多个附件),支持到服务器的ssl连接 * 需要的php扩展:sockets、Fileinfo和openssl。 * 编码格式是UTF-8,传输编码格式是base64 * @example * $mail = new MySendMail(); * $mail->setServer("smtp@126.com", "XXXXX@126.com", "XXXXX"); //设置smtp服务器,普通连接方式 * $mail->setServer("smtp.gmail.com", "XXXXX@gmail.com", "XXXXX", 465, true); //设置smtp服务器,到服务器的SSL连接 * $mail->setFrom("XXXXX"); //设置发件人 * $mail->setReceiver("XXXXX"); //设置收件人,多个收件人,调用多次 * $mail->setCc("XXXX"); //设置抄送,多个抄送,调用多次 * $mail->setBcc("XXXXX"); //设置秘密抄送,多个秘密抄送,调用多次 * $mail->addAttachment("XXXX"); //添加附件,多个附件,调用多次 * $mail->setMail("test", "<b>test</b>"); //设置邮件主题、内容 * $mail->sendMail(); //发送 */ class MySendMail { /** * @var string 邮件传输代理用户名 * @access protected */ protected $_userName; /** * @var string 邮件传输代理密码 * @access protected */ protected $_password; /** * @var string 邮件传输代理服务器地址 * @access protected */ protected $_sendServer; /** * @var int 邮件传输代理服务器端口 * @access protected */ protected $_port; /** * @var string 发件人 * @access protected */ protected $_from; /** * @var array 收件人 * @access protected */ protected $_to = array(); /** * @var array 抄送 * @access protected */ protected $_cc = array(); /** * @var array 秘密抄送 * @access protected */ protected $_bcc = array(); /** * @var string 主题 * @access protected */ protected $_subject; /** * @var string 邮件正文 * @access protected */ protected $_body; /** * @var array 附件 * @access protected */ protected $_attachment = array(); /** * @var reource socket资源 * @access protected */ protected $_socket; /** * @var reource 是否是安全连接 * @access protected */ protected $_isSecurity; /** * @var string 错误信息 * @access protected */ protected $_errorMessage; /** * 设置邮件传输代理,如果是可以匿名发送有邮件的服务器,只需传递代理服务器地址就行 * @access public * @param string $server 代理服务器的ip或者域名 * @param string $username 认证账号 * @param string $password 认证密码 * @param int $port 代理服务器的端口,smtp默认25号端口 * @param boolean $isSecurity 到服务器的连接是否为安全连接,默认false * @return boolean */ public function setServer($server, $username="", $password="", $port=25, $isSecurity=false) { $this->_sendServer = $server; $this->_port = $port; $this->_isSecurity = $isSecurity; $this->_userName = empty($username) ?

方法二:申请解封TCP 25 端口 (Outbound)

注意:在正式申请前,您需要确认同意并承诺,保证TCP 25 端口仅用来连接第三方的SMTP服务器,并从第三方的SMTP服务器外发邮件。如发现您使用申请的IP直接通过SMTP发送邮件,阿里云有权永久性封禁TCP 25端口,并不再提供解封服务。

操作流程:登录阿里云后台——控制台——安全管理——25端口解封——填写表单——约一个工作日便有结果.....
