Hello  EveryOne,

SendMail function working on local server,

But not on main server.

Thanks In Advance 

Hello,

What type of error you received?

Regards

Hello, Which one namespace are using to send an email like System.web.mail or System.net Mail......?

May be your SMTP server required authentication means Username and password to send a mail.....

well if you are working System.web.Mail.SMtpMail class to send mail it should work bcs it's not need to authenticate on SMTP server.. if you are working on  System.net Mail then it's required authentication......

Tell me which one class you are using and if feasible then paste your code.....  

thanks for reply,

i am using this namespace. 

using System.Net.Mail;

Anand you need autheticate on SMTP server ....

             MailMessage _mail = new MailMessage();

              _mail.From = new MailAddress(senderEmailID, sendername);
                    _mail.To.Add(_toEmailID);
                    _mail.Subject = _mailsubjectsubject;
                    _mail.Body = _emailbody;
 

                SmtpClient mailClient = new SmtpClient(ServerName,25);
                    _mail.Priority = MailPriority.Normal;
                    _mail.IsBodyHtml = _isHTMLBody;
                    mailClient.DeliveryMethod = SmtpDeliveryMethod.Network;
                    mailClient.Credentials = new NetworkCredential(username, passwd);
                    mailClient.Send(_mail);

try to use like this.......

i hope your problem will solve....... 

 Ok,

But client is not being ready to give his network username and pwd 

 If client is not ready to share SMTP server details so you should use System.web.Mail namespace to send a mail.....it doesn't require any authentication......Cheers
