send mail message error

every 17 messages I get an error "Send-MailMessage : Service not available, closing transmission channel. The server response was: Error: too many messages in one session" I think it is because I have connected to the smtp server to many times and I have not disposed any of the sessions. Do you think this error is because I have not disposed the sessions? And how would i go about disposing the sessions?

  $Fname = $_.FirstName
  $Lname = $_.LastName
  $EmpID = $_.EID
$MyEmail = "powershell@homelab.com"
$SMTP= "172.24.225.222"
$To = "administrator@homelab.com"
$Subject = "Create Email Script"
$Body = "reply 
ADD NETWORK 	$LogonName	`"$Fname`"	`"`"	`"$Lname`"	`"`"	changenow	`"Requested by:HR \r Created by:Automation`"	$EmpID	`"`"	2	`"$EmailGroup`"	`"cs staff`" 
PUT	USER	$LogonName	1252	0	$LogonName"
Start-Sleep 2
Send-MailMessage -To $to -From $MyEmail -Subject $Subject -Body $Body -SmtpServer $SMTP -Port 25 -DeliveryNotificationOption never

logon to your smtp server 172.24.225.222 and open IIS manager, close current sessions and then try again
Try to increase the "limit to no of connections"
do you have any open powershell sessions? close if any left

check the smtp properties in IIS manager, -> Messages > check or increase the counts

Thanks. The other admin white listed the email address we are using to send the emails and this seems to have stopped the error message from popping up. But I still have concerns that I am leaving connections open every time I send an email.

You should use the dispose() to close any open sessions :

$SMTPClient = new-object system.net.mail.smtpclient
$MailMessage = new-object system.net.mail.mailmessage

$SMTPClient.Host = $SMTPHost
$MailMessage.From = $Sender
$MailMessage.To.Add($Recipients)
$MailMessage.Subject = "TEXT HERE"
$MailMessage.Body = "BODY TEXT HERE"

$SMTPClient.Send($MailMessage)
$MailMessage.Dispose()
