one solution I found without installing anything, was to use gmail. as it is discussed over here http://forums.asp.net/t/1124257.aspx/1 it works pretty well so far for development purposes.
so from that post.
This is what the mail setting in the web config should look like :
<system.net>
<mailSettings>
<smtp deliveryMethod="Network" from="username@gmail.com">
<network defaultCredentials="false" host="smtp.gmail.com" port="587" userName=username" password="xxxxxxxxxxxx" />
</smtp>
</mailSettings>
</system.net>
aspx page :
<asp:PasswordRecovery ID="PasswordRecovery1" runat="server"
onsendingmail="PasswordRecovery1_SendingMail">
</asp:PasswordRecovery>
code behind (C#):
protected void PasswordRecovery1_SendingMail(object sender, MailMessageEventArgs e)
{
MailMessage mm = new MailMessage();
mm.From = e.Message.From;
mm.Subject = e.Message.Subject.ToString();
mm.To.Add(e.Message.To[0]);
mm.Body = e.Message.Body;
SmtpClient smtp = new SmtpClient();
smtp.EnableSsl = true;
smtp.Send(mm);
e.Cancel = true;
}
