scriptblock not returning any value - powershell

Question

In the below script $recexternal and $recinternal always return zero as if there are some issues with the second block.
However, the first executes successfully and gets correct $i and $e output.
What am I doing wrong?
Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010
$e = 0;
$i = 0;
$recexternal = 0;
$recinternal = 0;
$array = #("JayanManniath.Nair#contoso.com")
foreach ($user in $array) {
$sender = Get-TransportServer |
Get-MessageTrackingLog -ResultSize Unlimited -Sender $user
$sender | %{
if (($_.Source -eq "SMTP") -and ($_.EventId -eq "SEND")) {$e++}
if (($_.Source -eq "STOREDRIVER") -and ($_.EventId -eq "DELIVER")) {$i++}
}
$recipient = Get-TransportServer |
Get-MessageTrackingLog -ResultSize Unlimited -Recipients $user
$reipient | %{
if (($_.Source -eq "SMTP") -and ($_.EventId -eq "RECEIVE")) {$recexternal++}
if (($_.Source -eq "STOREDRIVER") -and ($_.EventId -eq "DELIVER" )) {$recinternal++}
}
}
Write-Host "$user has sent $i emails internally"
Write-Host "$user has sent $e emails externally"
Write-Host "$user has received $recexternal emails from outside organization"
Write-Host "$user has received $recinternal emails from inside the organization"

Answer 1

Aside from the obvious typo your code has the output placed wrongly,
in case of more than one $user in $array the Write-Host commands
should be placed inside the ForEach.
A Where-Object and ().count instead of
the ForEach-Object (%) and the IFs is possibly more efficient.

$array = #("JayanManniath.Nair#contoso.com")
ForEach ($user in $array) {
$sender = Get-TransportServer |
Get-MessageTrackingLog -ResultSize Unlimited -Sender $user
$e = ($sender | Where-Object {($_.Source -eq "SMTP") -and
($_.EventId -eq "SEND")} ).Count
$i = ($sender | Where-Object {($_.Source -eq "STOREDRIVER") -and
($_.EventId -eq "DELIVER")} ).Count
$recipient = Get-TransportServer |
Get-MessageTrackingLog -ResultSize Unlimited -Recipients $user
$recexternal = ($recipient | Where-Object {($_.Source -eq "SMTP") -and
($_.EventId -eq "RECEIVE")} ).Count
$recinternal = ($recipient | Where-Object {($_.Source -eq "STOREDRIVER") -and
($_.EventId -eq "DELIVER")} ).Count
Write-Host "$user has sent $i emails internally"
Write-Host "$user has sent $e emails externally"
Write-Host "$user has received $recexternal emails from outside organization"
Write-Host "$user has received $recinternal emails from inside the organization"
