Question : Is it Possible in Exchange 2007 to Globally change certain values?

I am growing very frustrated with a particular aspect of Exchange 2007 (Even with SP1)

In Exchange 2003 when you mail-enabled distribution groups, they would work without issue; In Exchange 2007 when you create mail-enabled distribution groups, you are required to set the -RequiredSenderAuthenticationEnabled flag via Powershell for EVERY distribution Group (I have about 100-150 of them) to be able to be sent mail from the Internet, internally they work fine.

Is there a way to change the global setting for all groups or is there a powershell shortcut to apply to all distribution groups (I tried an asterik and it didn't work.)

This worked for me

Get-DistributionGroup | Set-DistributionGroup -RequireSenderAuthenticationEnabled $true
