net发送邮件2

6，用需要Smtp验证的邮箱发信
现在为了防止垃圾邮件，绝大部分Smtp服务器需要验证了
发信方法如下：
[ C# ]

     MailMessage mail = new MailMessage();
     mail.To = "me@mycompany.com";
     mail.From = "abc@126.com";
     mail.Subject = "this is a test email.";
     mail.Body = "Some text goes here";
     mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");    //basic authentication
     mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "abc"); //set your username here
     mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "your password");    //set your password here

     SmtpMail.SmtpServer = "smtp.126.com";  //your real server goes here
     SmtpMail.Send( mail );

[ VB.NET ]
    Dim mail As New MailMessage()
    mail.To = "me@mycompany.com"
    mail.From = "abc@126.com"
    mail.Subject = "this is a test email."
    mail.Body = "Some text goes here"
    mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1") 'basic authentication
    mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "abc") 'set your username here
    mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "Your Password") 'set your password here
    SmtpMail.SmtpServer = "smtp.126.com" 'your real server goes here
    SmtpMail.Send(mail)

7,修改smtp服务器的端口，以及使用SSL加密
大部分smtp服务器的端口是25，但有些却不是
同时，绝大部分Smtp服务器不需要SSL登陆，有些却需要
比如Gmail，smtp端口是：465，同时支持SSL
代码如下：

[ C# ]

     MailMessage mail = new MailMessage();
     mail.To = "me@mycompany.com";
     mail.From = "abc@126.com";
     mail.Subject = "this is a test email.";
     mail.Body = "Some text goes here";
     mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");    //basic authentication
     mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "abc"); //set your username here
     mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "your password");    //set your password here
    
     mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport",465);
     mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", "true");

     SmtpMail.SmtpServer = "smtp.126.com";  //your real server goes here
     SmtpMail.Send( mail );

[ VB.NET ]

    Dim mail As New MailMessage()
    mail.To = "me@mycompany.com"
    mail.From = "abc@126.com"
    mail.Subject = "this is a test email."
    mail.Body = "Some text goes here"
    mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1") 'basic authentication
    mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "abc") 'set your username here
    mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "Your Password") 'set your password here
   
    mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport",465)
    mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", "true")

    SmtpMail.SmtpServer = "smtp.126.com" 'your real server goes here
    SmtpMail.Send(mail)
