You simply need to configure ISA server to "server publish" your Exchange Server. The infamous Tom Shinder has an article all about it at http://www.isaserver.org/shinder/tutorials/publishing_a_mail_Server_with_isa_server.htm Nick Chadwick Development & Technical Support Manager Comsoft Limited, UK Tel: +44-(0)20-8240-4452 Fax: +44-(0)20-8240-4449 Mobile: +44-(0)7740-362408 Email: nick@xxxxxxxxxxxxxx <mailto:nick@xxxxxxxxxxxxxx> Web: http://www.comsoft.ltd.uk/ -----Original Message----- From: Donald Coleman [mailto:dcoleman@xxxxxxxxxx] Sent: 26 September 2001 03:17 To: [ISAserver.org Discussion List] Subject: [isalist] Exchange Server 5.5 behind ISA server?????? http://www.ISAserver.org We now have Exchange server 5.5 behind our Microsoft Proxy Server. We intend to upgrade to ISA Server but I have no idea how to configure Exchange. In the case of MSP 2.0, I made several wspcfg.ini files with appropriate changes so that SMTP/POP3 would work. What do I do in the case of ISA?? ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: nick@xxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ********************************************************************** Disclaimer: This e-mail contains proprietary information some or all of which may be legally privileged.
