We are setup with exchange 2010 on prem hybrid connected to o365. Our front end 
anti-spam is EOP

We have a DL that has user objects and a contact. The contact has an internal 
email address to route to a web app. Example 
[email protected]<mailto:[email protected]>

My question is when external emails are routed through EOP, is the DL expanded 
and the contact is parsed to see if it is a valid email? Because it seems like 
since we moved to EOP the email to the contact is not being delivered but to 
the user objects it is.

Thanks,jb
