在开始使用 PHP 发送邮件之前, 需要先在邮箱设置开启 smtp, 拿到 SMTP 服务器的授权码
腾讯 QQ 邮箱 (推荐):smtp.qq.com smtp/pop3 开启: (注意腾讯邮箱要单独设置安全码 点击查看说明)
网易 163 邮箱: smtp.163.NET smtp/pop3 开启:(注意网易免费邮箱 smtp 密码要单独设置 点击查看说明)
新浪免费邮箱: smtp.sina.com smtp/pop3 开启: http://mail.sina.com.cn/help2/client01.html
腾讯企业邮箱: smtp.exmail.qq.com
雅虎免费邮箱: smtp.mail.yahoo.cn
网易 126 邮箱: smtp.126.com
搜狐免费邮箱: smtp.sohu.com
