使用CDO发送邮件

引用CDO组件，SYSTEM32下的CDOSYS。DLL，增加一个包装器

using CDO;

//本例使用CDO来实现发送邮件，可带验证,此示例在活动目录内向外网发送邮件成功 profession2k office2k office2k3下通过 VS2,2,VS2k3,要引用CDOSYS
Configuration conf=new Configuration();
//以下部分设置参数(服务器,端号，用户名，密码，发送邮件帐号，回复邮箱帐号)
conf.Fields[CdoConfiguration.cdoSendUsingMethod].Value=CdoSendUsing.cdoSendUsingPort;
conf.Fields[CdoConfiguration.cdoSMTPServer].Value="smtp.21cn.com";
conf.Fields[CdoConfiguration.cdoSMTPServerPort].Value=25;
conf.Fields[CdoConfiguration.cdoSMTPAccountName].Value="[e-mail]";
conf.Fields[CdoConfiguration.cdoSendUserReplyEmailAddress].Value="/"greystar/" <[e-mail]>";
conf.Fields[CdoConfiguration.cdoSendEmailAddress].Value="/"greystar/" <[e-mail]>";
conf.Fields[CdoConfiguration.cdoSMTPAuthenticate].Value=CdoProtocolsAuthentication.cdoBasic;
conf.Fields[CdoConfiguration.cdoSendUserName].Value="[e-mail]";
conf.Fields[CdoConfiguration.cdoSendPassword].Value="XXXXXXX";

conf.Fields.Update();
MessageClass msg=new MessageClass();

msg.Configuration=conf;

msg.To="[e-mail]";
