<?php

    include_once ("Swift/Authenticator/LOGIN.php");
    //收件人的地址
    $receive_mail="[email protected]";
    // 创建smtp连接,由于发送邮件的邮箱smtp地址和端口
    $smtp = new Swift_Connection_SMTP('smtp.sina.com', 25);
    // 设置用于发送邮件的邮箱账号
    $smtp->setUsername('[email protected]');
    // 设置发件箱的邮箱登陆密码
    $smtp->setPassword('1qaz2wsx');
    //添加ssl连接支持，如果没此项，发送到gmail等需要ssl连接的邮箱就会失败,但是开启此选项会影响邮件发送的速度
