Hello everyone,

I'm really stuck right now and I hope someone here can help me.  Our site sends many emails at one time for notificaitons.  When we send the emails, not all emails are sent.  For example we need to send 200 emails out.  We call the DotNetNuke.Services.Mail client to do this.  The issue is that after a certain number (Which seems random) the system stops sending.  We are using Google and they said the issue may be that we should use just one email client to send the emails.  

It seem that DNN creates a new client every time an email is sent

 using (var smtpClient = CreateSmtpClient(smtpInfo, host, port))
 {

     foreach(var mailMessage in messages){
          smtpClient.Send(mailMessage);

     }
 }

Is there a method to use where a single SMTP client is created, THEN the emails are sent?

After a number of emails are sent (In this example 91 were successfully sent) then the following error is registered for each of the next 99 emails:
