Question

我想创建可以通过usibg javaMail API发送恢复密码的代码，从我的官方域名地址发送，如abc@xyz.com。

我做了一些编码，比如使用smtp.gmail.com

此 BLOG我提到发送邮件到任何用户电子邮件地址。

this structure i want:

 from : deepu@exxxxtechnology.com-----( not deepu@gmail.com  )
 to: anyuser@anydomain.com, user@gmail.com / user@hotmail.com /user@yahoomail.com

 is it possible ?
