以QQ邮箱为例
需要开启SMTP服务设置授权码。授权码不是登录密码授权码是QQ邮箱用于登录第三方客户端/服务的专用密码适用于登录以下服务POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV 服务。不同邮箱可能不一样。
还需要服务器地址QQ 邮箱的服务器地址 (host) 是:
收信服务器 (POP3) : pop.qq.com
发信服务器 (SMTP) : smtp.qq.com 二、代码编写 1、配置文件
可以将邮件的账号密码等放入配置文件
#邮件配置需要修改密码。username账号password密码/授权码serverUrl服务器地址serverPort服务器端口sendMail邮箱
email:username: 1074004100qq.compassword:serverUrl: smtp.qq.comserverPort: 25sendMail: 1074004100qq.com
