Hi everyone,

I have been searching the net but couldnt find a solution to my
problem of sending emails to external domains in Asp.net 1.1.

I am not getting any error and the Mail Send message returns 1 or
success but the mail doesnt go. I am using the Mail Server as the
Companies Exchange Server which has full rights to send emails to any
domain. This is proved by the fact that if I sent email through
outlook to hotmail,gmail etc , it works fine. Also I have created a
user in the Exchange Server will full rights but still the problem
persists. I have copied my code below to give you an idea.

MailMessage objMsg = new MailMessage();

    objMsg.From ="abc@xyz.com";
    objMsg.Subject = objMailDM.MailSubject;
    objMsg.Body += objMailDM.MailBody;
    objMsg.To ="123@xyz.com";

    SmtpMail.SmtpServer =
ConfigurationSettings.AppSettings["MailServer"]; //this entry will go
to web.config
    // set SMTP server port
objMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/
smtpserverport",25);
objMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/
sendusing",2);
//objMsg.BodyFormat = System.Web.Mail.MailFormat.Html;
objMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/
smtpauthenticate",1);
objMsg.Fields.Add"http://schemas.microsoft.com/cdo/configuration/
sendusername", "username");
objMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/
sendpassword", "pass");
                try
                {
                    SmtpMail.Send(objMsg);
                    return 1;
                }
