All incoming mail gets to ISA is scanned by GFI MailEssentials and MailSecurity then passed on to Exchange 2000. For out bound mails Exchange passed on to the ISA machine for scanning and sending out to the net. Can anyone explain why my Exchange only sends mail with the firewall client disabled? Do I need to use the Firewall client? Can someone tell me when I do and when I don't need the Firewall client? Awaiting your appreciated advice William ------------------------------------------------------ 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 ------------------------------------------------------ Exchange Server Resource Site: http://www.msexchange.org/ Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
