Exchange 2010 - email list of all distribution groups, members, and owner

I recently had to update a script that I used to use in exchange 2007 that no longer works in 2010. It's mainly due to powershell changes and a tricky issue with getting the owner field back out. Anyway, this script cycles through all your email distribution groups, then emails a list of all of them, the members of each, and the owner to the email distribution group. It's similar to an old script I had back in 3/08.

Updated Note: You can also use
# grab the first owner from the multivalued property
$gOwner = get-user -Identity $group.ManagedBy[0]
instead to get the group owner property and then just use that .Name property for string ouput.

# Enumerates all members of all Distribution Lists in Exchange 2010.
# Use PowerShell.exe -command ". 'D:\Program Files\Microsoft\Exchange
# Server\V14\bin\RemoteExchange.ps1'; Connect-ExchangeServer
#-auto; replacewithyourscriptfilenameandpath"

# Script will then proceed to email a list of all
# members of each group

#first get all distributionlists
$dl = get-distributiongroup

# initialize variables
$recipient = "PickARecipientEmailAddress"
$sender = "PickASMTPSenderEmailAddress"
$subject = "Monthly Summary of Email Groups"
$server = "YourSMTPServerGoesHere"
$gOwner = "blankstring"

#prepare and output file
$currDate = get-date
#path must exist
write-host "Email groups as of: " $currDate | out-file 'c:\temp\emailgroupmembers.txt'

#then enumerate through them all and get all group members.
foreach ($group in $dl) {

$groupName = "-------------" + "`r`n" + "Group Name: " + $
write-host $groupName -foregroundcolor Green
# this part joins the results of that field into one string.
$gOwner = $group.ManagedBy | `
Select @{Name='Name';Expression={[string]::join(";", ($_.Name))}}
write-host "Owner: " $gOwner -foregroundcolor Green
$groupName | out-file -append 'c:\temp\emailgroupmembers.txt'
$group.ManagedBy.Name | out-file -append 'c:\temp\emailgroupmembers.txt'
$groupAddr = "Email Address: " + $group.PrimarySMTPAddress
$dlgm = get-distributionGroupMember $
$dlgm | fw | out-file -append 'c:\temp\emailgroupmembers.txt'

#Note: `r`n is a carriage return
$bText0 = "-------------" + "`r`n" + "Group Name: " + $group.Name
$bText1 = "`r`nOwner:" + $gOwner + "`r`n"
$bText2 = $groupAddr.ToString() + "`r`n"
$bText3 = "`r`n" + "group members: `r`n"
$bText4 = $dlgm | fl Name | out-String
$bTextFinal = $bText0 + $bText1 + $bText2 + $bText3 +$bText4

$body = $body + $bTextFinal

$msg = new-object System.Net.Mail.MailMessage $sender, $recipient, $subject, $body

#send email
$client = new-object System.Net.Mail.SmtpClient $server
$client.credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials

To call it from a batch file: (avoid long path names, spaces, etc)
PowerShell.exe -command ". 'D:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'; Connect-ExchangeServer -auto; D:\Exch2010enum.ps1"
