I have 2 ironports, working together for receiving mail but with different configurations regarding outgoing smtp authentication.
We are gradually trying to migrate all users to the authenticated solution, and I need a way to understand who is still using the old configuration.
Of course the interfaces have diffent names and I can see which appliance was used from logs or MFC, but this is not practical for a couple of thousand mailboxes.
I would also need to create periodical reports to see the migration progress.
Any idea? Filters, Policies, Labels?
