Never whitelist your own domain. 
If you have problems with your own domain mails getting marked spam , 
Either 

1) Try routing your outgoing mails such a way that an internal mails
does not go through the scan 

2) If mails from "universitycoop.com" must get scanned ask all users to
send on an smtp-authed session, and your MTA will add headers which can
be used for whitelisting 

3) Or simply use SPF records and whitelist_from_spf , you could even
reject mails that dont pass SPF, so that these mails are blocked right
at the gate
