Naybe there is some problem with your server, as far as I know, the 163.com SMTP need to authentication, please try with your own serer or others.

MailMessage.From ,MailMessage.To 必须保证非空！

[Doninet]

是非空呀！！

163的SMTP需要账号和密码才可以使用，找一个不需要账号和密码的SMTP服务器，就可以了。

[Doninet]

哪儿有这样的服务器呀？？

我自己能不能做帐号和密码的验证！！！

[aaxu]

WebMail不支持SMTP服务器账号和密码的验证，只能用不需要账号和密码验证的SMTP.可以用Jmail。

webmail不支持SMTP的帐号和密码,我这里有不需要帐号和密码验证的SMTP:[e-mail]
