I have a server setup with ISA and Exchange 2000. I am trying to setup Site & Content Rules. I setup a rule allow Domain Users access to all destinations and all content. I am allowing all protocols to any request. When I enable my Site Rule, SOME of my out going emails get hung up in the Exchange SMTP Que. If I open my rules up to allow any request to all destinations (anonymous access), the emails go out without any problems. I am missing something. Any ideas why only some messages get stuck? Thanks Russ
