Sorry, I wasn't overly clear with my query :)

You are 100% correct with your statements. I was looking to allow Xeams to identify the primary exchange address - or allow the Xeams admin to select the "association email address" to identify the user in reports so that it becomes clearer who is who.

ie.

Using the example above the user reports will contain:

Jason@domain.local
Chris@domain.local
Peter@domain.local 

instead of

backups@domain.local
accounts@domain.local
ebay_admin@domain.local

Does this clarify my question?

My next question would then be, can a report be created to indicate the volume of emails processed to each individual association address? For example to assist with identifying which email addresses may have been compromised for spam?

Kind regards
Jason
