Changing DL setting for every DL in the company?

You can simply preview the result of the cmdlet execution by using the -WhatIf switch. Not all cmdlets support it though, so be careful. Anyway, here's an example that updates all groups to allow external senders:

If you want to run it against a subset of the groups, use the filter parameter or import the list of groups from CSV, etc.
