My company runs Exchange 5.5 SP4 and has been blackholed by the ORDB.org. I’ve been trying everything I can lay my hands on to shut off this Exchange capability without shutting off my users or our clients from email. I have 12 remote offices usinglocal ISP for internet connectivity, some use the ISP’s SMTP server, the rest have to use my Exchange server. All user Outlook configs are Internet Email, not Exchange server. I have tried configuring the IMS Connections tab to “Clients can only submit if homed on this server” but then outside clients can’t send us email. I’m out of options. Any help would be appreciated.
