This is how it is configured:
Servers: Script blocking, Exchange 2000/2003, MS SMTP 2000/2003, Network shield, Standard shield, Web shield providers. (Of course the Exchange plug-ins are only on exchange server)
Workstations: Script blocking, Network shield, Standard shield, Web shield, and Outlook/Exchange providers.

My question is: are any of these providers redundant between the servers and workstations or could any of them cause potential conflicts?
Also, some of the workstations use POP3/SMTP from an ISP outside of this organization for accessing mail in addition to Exchange. Do they need to have the Internet Mail provider as well?
