Hi Barry, Why did you install the Firewall client on the Exchange Server? I'd get rid of that first. Also, I'm not sure what you mean by "re-routed". All outbound mail leaves the Exchange Server to either an SMTP relay or if the Exchange Server doesn't use a outbound relay, then it sends the mail directly to the destination SMTP server. Thanks!

Everything was working OK. I then decided to upgrade all of my workstations (& exchange server) to Firewall Clients. Downloaded the white paper from isaserver.org. Did as instructed. Everything SEEMED to be OK and working perfectly. Shortly afterwards, I was not able to send emails. I could receive, but not send. (Though I could reply). I could surf the Internet OK. No problems! Shortly after that, I found out that I could only send emails to addresses that weren't re-routed to another email address. (This appeared to be why 'Reply' worked as it always sends the email to the final destination directly). I disabled all of the firewall client connections and reverted back to web access clients. (My original configuration - which worked). That didn't help! I checked everything I could think of. Nothing had changed from my original "working" configuration. I GIVE UP! Can anyone offer any clues as to what is going on? ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=isalist
