毕业设计做网站 服务器怎么弄网页设计和网站制作

1，开启服务，获取授权码。以QQ邮箱为例：

点击管理服务，进入账号与安全页面

 2，相关设置参数，以QQ邮箱为例：

登录时，请在第三方客户端的密码输入框里面填入授权码进行验证。（不是填入QQ的密码）
IMAP/SMTP 设置方法用户名/帐户： 你的QQ邮箱完整的地址密码： 生成的授权码电子邮件地址： 你的QQ邮箱的完整邮件地址接收邮件服务器： imap.qq.com，使用SSL，端口号993发送邮件服务器： smtp.qq.com，使用SSL，端口号587POP3/SMTP 设置方法用户名/帐户： 你的QQ邮箱完整的地址密码： 生成的授权码电子邮件地址： 你的QQ邮箱的完整邮件地址接收邮件服务器： pop.qq.com，使用SSL，端口号995发送邮件服务器： smtp.qq.com，使用SSL，端口号587

3，2次包装代码：

4，邮件效果：

特别说明：若要实现：

第1，正文带有背景图片。
第2，正文为自定义编辑风格（带有边框，不同颜色的字体）。
正文需要为html格式，普通文本格式无法实现。
