Hi

i'm trying to send email through my gmail account, used to work

web.config

 <system.net>
   <mailSettings>
     <smtp from="myfrom" >
       <network defaultCredentials="true" host="smtp.gmail.com"
port="465" userName="mygmailusername" password="mygmailpassword"/>
     </smtp>
   </mailSettings>
 </system.net>

my fonction

public static void SendEmail(string To, string From, string Subject,
string Body, bool IsBodyHtml)
       {
           try
           {
               using (MailMessage message = new MailMessage(From, To,
Subject, Body))
               {
                   message.IsBodyHtml = IsBodyHtml;
                   SmtpClient mailClient = new SmtpClient();
                   mailClient.Send(message);
               }
           }
           catch (SmtpException ex)
           {
               throw new ApplicationException("SmtpException has
Occured: " + ex.Message);
           }
       }

i get either error :
1-
SmtpException has Occured: The SMTP server requires a secure
connection or the client was not authenticated. The server response
was: 5.7.0 Must issue a STARTTLS command first e13sm6192679qba.37

or
2 -  when i enable ssl
SmtpException has Occured: The SMTP server requires a secure
connection or the client was not authenticated. The server response
was: 5.5.1 Authentication Required e11sm6169311qbc.5

who can it be solved ?
also who can i use this account to send email through the password
recovery control ?
thanks
