Sent item track

Hello guys,
Need help one more time.
this is the script i am running to get All the Sent items for specific time proud.

Get-TransportServer | Get-MessageTrackingLog -EventId Send -Start "$startDateFormatted 00:00:00" -End "$endDateFormatted 23:59:59" -resultsize unlimited 

This script is working fine. but i would like to know the Specific Domain name sent items. or i would like to know what is the total sent item for internal.
Say as example my domain is ABC.com. i would like to know what is the total sent items for ABC.com to ABC.com (Total Sent items only). Please advise how to do this.
Thank you looking forward.

Assuming your output has a Domain property, you would use Group-Object:

$obj = @()
$obj += [pscustomobject]@{Date=(Get-Date);Domain="abc.com";Sender="John";}
$obj += [pscustomobject]@{Date=(Get-Date);Domain="abc.com";Sender="Lisa";}
$obj += [pscustomobject]@{Date=(Get-Date);Domain="xyz.com";Sender="Lisa";}
$obj += [pscustomobject]@{Date=(Get-Date);Domain="www.com";Sender="John";}

$obj | Group-Object -Property Domain -NoElement

Output:

Count Name                     
----- ----                     
    2 abc.com                  
    1 xyz.com                  
    1 www.com  

Thanks for your reply,

This is my Script

#Powershell 
$nl = [Environment]::NewLine
 
#Mailbox to gather stats on
#$mailbox=""
 
#Get todays date twice
$startDate=Get-Date
$endDate=Get-Date
$domain= "aniyanetworks.net"
 
#Subtract 1 day from todays date (report ending day) and 7 days from todays date (report starting day)
$startDateFormatted=$startDate.AddDays(-32).ToShortDateString()
$endDateFormatted=$endDate.AddDays(-1).ToShortDateString()
 
 
#Who to send the e-mail report to.
#Multiple e-mail addresses should be in this format ", "
$emailFrom = "Monthly-Email-Tracking@aniyanetworks.net"
$emailTo = "sysadmin@aniyanetworks.net"
$subject = "Monthly e-mail report for $domain for $startDateFormatted - $endDateFormatted"
$smtpServer = "exchange1.aniyanetworks.net"
 
 
# Sent e-mails
#$sendCount = Get-TransportServer | Get-MessageTrackingLog -Start "$startDateFormatted 00:00:00" -End "$endDateFormatted 23:59:59" -Sender $mailbox -resultsize unlimited | select-object -unique MessageId
$sendCount = Get-TransportServer | Get-MessageTrackingLog -EventId Send -Start "$startDateFormatted 00:00:00" -End "$endDateFormatted 23:59:59" -resultsize unlimited
#$sendCount = Get-TransportServer | Get-MessageTrackingLog -EventId Send -Start "03/14/2016 00:00:00" -End "04/14/2016 23:59:59" -resultsize unlimited
#$sendCount.count
# Received e-mails - This works but not on generic accounts
#$receiveCount = Get-TransportServer | Get-MessageTrackingLog -Start "$startDateFormatted 00:00:00" -End "$endDateFormatted 23:59:59" -Recipients $mailbox -resultsize unlimited | select-object -unique MessageId
 
$sendCountString = $sendCount.count

So this will give me Total Count of all the Sent items.
but i would like to know only my domain to my domain sent items.
such as , from *@aniyanetworks.net to *@aniyanetworks.net
please advise.
