配置文件：

<appSettings> <add key="kkadf" value="sd" /><add key="SmtpHost" value="smtp.gmail.com"/><add key="SmtpPort" value="587"/><add key="SmtpUser" value="[e-mail]"/><add key="SmtpPassword" value="********"/></appSettings>

 

调用方法：

protected void Button1_Click(object sender, EventArgs e) { Mail mail = new Mail("[e-mail]", "aaaa", "aaaaaa"); mail.Send(); //使用465端口就会发生超时的错误.使用587就不会.奇怪.不过使用FoxMail来用465端口发信就正常 }
