Could someone with more skills than me complete this script to send a -email alert when I get a false  response of the port not being available.

I have the send mail function ready but can´t get it to trigger on the false response.

Script is this:

# Test-Port_21.ps1
# Does a TCP connection on specified port
$ErrorActionPreference = "SilentlyContinue"

# Gets the date
$a = Get-Date
# Create TCP Client
$tcpclient = new-Object system.Net.Sockets.TcpClient
# Tell TCP Client to connect to machine on Port
$iar = $tcpclient.BeginConnect($srv,$port,$null,$null)
# Set the wait time
$wait = $iar.AsyncWaitHandle.WaitOne($timeout,$false)
# Check to see if the connection is done
    # Close the connection and report timeout
    if($verbose){Write-Host "Connection Timeout"}
    Return $false
    # Close the connection and report the error if there is one
    $tcpclient.EndConnect($iar) | out-Null
    if(!$?){if($verbose){write-host $error[0]};$failed = $true}

# Return $true if connection Establish else $False
if($failed){return $false,$a}else{return $true,$a}

The Send mail function I want to use is:

      $emailFrom = "X"
      $emailTo = "X"
      $subject = "Port 21 unavailable"
      $body = "X"
      $smtpServer = "X"
      $smtp = new-object Net.Mail.SmtpClient($smtpServer)
      $smtp.Send($emailFrom, $emailTo, $subject, $body)

Many Thanks!!
