在Exchange Server环境下发送邮件(通过CDO组件)

1. 先添加COM 引用 "Microsoft CDO for Windows 2000 Library"

2.代码

        public static void ProxySendMail()
        {
            CDO.Message msg = new CDO.Message();
            string user="gpaft";
            string passWord = "!QAZ1qaz";
            string from = "gpaft@grouppower.local";
            string to = "dingfeng_wu@163.com";
            string reply="dingfeng_wu@yahoo.com.cn";
            string server = "192.168.1.127";
            msg.From = from;
            msg.To = to;
            msg.Subject = "代理发送测试";
            msg.TextBody = "代理测试内容.";

            CDO.IConfiguration iConfig = msg.Configuration;

            ADODB.Fields fields = iConfig.Fields;


            fields["http://schemas.microsoft.com/cdo/configuration/sendusing"].Value = 2;

            fields["http://schemas.microsoft.com/cdo/configuration/sendemailaddress"].Value = from;

            fields["http://schemas.microsoft.com/cdo/configuration/sendpassword"].Value = passWord;

            fields["http://schemas.microsoft.com/cdo/configuration/smtpauthenticate"].Value = 2;

            fields["http://schemas.microsoft.com/cdo/configuration/smtpserver"].Value = server;

            fields["http://schemas.microsoft.com/cdo/configuration/smtpaccountname"].Value = user;

            fields["http://schemas.microsoft.com/cdo/configuration/smtpuserreplyemailaddress"].Value = reply;

            fields["http://schemas.microsoft.com/cdo/configuration/sendusername"].Value = user;


            fields.Update();

            try
            {

                msg.Send();

                msg = null;

            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            Console.ReadKey();
        }

注:

fields 的smtpauthenticate 属性的取值也是挺有意思的, 当它取0时, 代表无需验证, 1代表基本的验证, 2是NTLM验证.

sendUsing 取2 的意思是, 强制通过smtpServer 属性指定的server 发送邮件.server属性设为exchange server 的IP 地址.

经测试,只要smtpauthenticate 设1时可以通过.
