Here is Configuration for Gmail As SMTP and In Code you have to Write Like Below to send mail; using System.Net.Mail; protected void PasswordRecovery1_SendingMail( object sender MailMessageEventArgs e) { SmtpClient client = new SmtpClient (); client.EnableSsl = true ; client.Send(e.Message); }

Mark Uy · Answer

hold on. this is on the password recovery control. is this the correct event to put the code you wrote? protected void PasswordRecovery1_SendingMail(object sender MailMessageEventArgs e) { }

Mark Uy · Answer

like what ive said im just using the asp.net website administration tool and the retrieve password logincontrol. so im practically not using any codes. the smtp settings inside the website administration tools asks only these options: Server Name: Server Port: * Server port should be a positive integer From: Authentication: None Basic Choose this option if your e-mail server requires you to explicitly pass a user name and password when sending an e-mail message. Sender's user name: Sender's password: NTLM (Windows authentication) Choose this option if your e-mail server is on a local area network and you connect to it using windows credentials. so i have no idea how to add a new set of code in there.
