So we do an import from AD every 1 day to keep our requestersdatabase up to date.
We fetch our request from an inbox. This al works great but

Suppose that i have 3 members in AD, person A, B and C. Now person D who is not in our AD, sends an email to our helpdesk-inbox. That member is automatically added to our requesterslist. How can we prevent this from happening. We want to receive the mail offcourse, but we don't want them in our requesterslist.

Please advise,

Kind regards
