How do I make ALL MAIL on my Exchange Server 2010, route through my Mirapoint Razor Gate. I have 2 mail servers, Exchange (wich is new) and Mirapoint. I want both mail systems to use AD for local mail routing. When mail is sent externally to my Razor Gate the mail delivers fine (to both Exchange and Mirapoint). When I send mail from Mirapoint to an Exchange user, it gets delivered fine (This is because ALL mail that is sent on the Mirapoint system is routed through our RazorGate for ANTI SPAM/ANTI Virus checks and local user routing). What happens is that if I send mail from Exchange and the account IS NOT on that server, the mail fails. Mail only routes through our RazorGate, from Exchange, when the domain name is not our domain. I need Exchange to route all mail through our RazorGate. Please Help !!!

Unfortunately this is not possible ,the categorizer process on the exchange server will never route the mail to another hob (like razor gate) if it found itself the Authoritative server for that domain and the user is reside within the same AD siteMCP, MCSE 2000 , MCSA 2000 ,MCSA 2003 , MCITP , MCTS , MCT

Mohamed, If he were to stamp the AD user accounts that are present on the RazorGate with a non-exchange configured domain and configured that domain on the razorgate I believe he could achieve his goal. For instance if exchange is configured with emailaddress@domain.com all users with mailboxes on the server would be stamped with the user@domain.com email address policy. Using scripting and ADSI edit he could configure the remaining RazorGate users to have an email address of user@razor.domain.com. He would then create a routing rule in exchange to route all traffic destined for razor.domain.com to the razorgate appliance. This is very similar to the practice that is done when migrating users to a new domain. I hope this helps Derek. -Chris Chris Raschke MCITP:EA | MCITP:EMA | MCSE | MCTS | Security+

Hi Yes, subdomains could be a solution that works. Just set up a send connector for the subdomain and route it to where it should? Razor or direct to the server(s) it should be and then do the opposite from the other serverJonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | Blog: http://www.testlabs.se/blog | Follow me on twitter: jonand82
