Ok Try this Idea Remove all those Mail Settings From Web.Config and Embed them in your Coding use Directly below Code to Send mail .csharpcode .csharpcode pre { font-size: small; color: black; font-family: Consolas Courier New Courier Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } protected void btnSendMail_Click( object sender EventArgs e) { SmtpClient sc = new SmtpClient( smtp.gmail.com  587); sc.EnableSsl = true ; sc.Credentials = new NetworkCredential( kirtan007@gmail.com  mypassword ); // Be Sure Where you Send mail to Check if Mail is Sent or Not MailMessage mail = new MailMessage( new MailAddress( kirtan007@gmail.com ) new MailAddress( kirtan007@gmail.com )); mail.Subject = Testing  ; mail.Body = Hello This IS Testing  ; sc.Send(mail); Response.Write( Mail Sent Successfully !! ); }

Hi  Not all fields are mandatory in web.config. Please find below code you need to update in web.config and ur application. Web.config: system.net > mailSettings > smtp > network host =  host server name  port =  25  defaultCredentials =  true  /> smtp > mailSettings > system.net > Application: SmtpClient smtp = new SmtpClient(); smtp.UseDefaultCredentials = true; MailMessage mailMessage = new MailMessage(); mailMessage.To.Add( new MailAddress( ToemailAdresss ToDisplayname); //create the mail message mailMessage.Subject = subject; mailMessage.Body = messageBody; mailMessage.From = new MailAddress( fromEmailAddress fromDisplayName ); smtp.Send( mailMessage ); for above to work please add System.Net and System.Net.Mail namespaces. Please mark this post as anwer if this is helpful. Happy Coding!! Wizkid

Hi Azeem Check Port No if you are using smtp.gmail.com server then Check the port in Web.Config Port = 587 and in Username =your gmail whole email Address like kirtan007@gmail.com and in password = your gmail account password and Be also make Sure that you have enabled POP support in your Gmail account if you not have enabled POP in gmail account Do it 1. Login to your gmail account 2. Click on Settings 3. go to Forwarding and POP/IMAP tab 4.Select radio button  Enable POP for all mail  Thanks Happy Coding :)

Thanks for your support i type nslookup on the command prompt as you set i got some message that Cannot find server name for ip address 192.168.56.200:non existent domain Default server:some name address: some ip address i got the above information

Roei Bar · Answer

hey the from is not a must field you can enter it dynamicaly from your code this is the from email address you must insert a valid email address that has send permissions on the host part you need to go to : command -> type nslookup -> set type=mx -> write down your mailserver name whatever you receive is the mailserver host this is the mx record
