I do your second choice already except I use 2003 server and Exchange, and ISA 2004 Server. I use OWA and RPC over HTTP. You can certainly publish POP3 if you intend to go that route.

My current exchange mail is not out sourced by another company, its hosted there and i am using here locally in my company which is located in Saudi arabia, Normal server exchange server 2000 enterprise edition, and installed on it POP3 Downloader to get all the E-mails from hosting company and distributed them back to internal. 3. you understand me wronge, i was trying to tell you what is my plan, i am sure i am understanding what i will do . 4. i purchased already one server and i purchased also one exchange server 2000 enterprise edition and i got also 1 ISA SERVER 2000 ENTERPRISE EDITION , AND I GOT ALSO 4 REAL IP-ADDRESS. untill now, i am understand what is going on, but due to some problems with my understanding with ISA server - because i did not work with ISA in Deepway- i am haveing 2 choice :- 1. the First choice is using ( FE & BE). and the front end will be the server who is running exchange server 2000 enterprise editon with Real IP-Address , but without holding any Data mailboxes for the user, while the back end , will be normal server installed on exchange server and have all the users mailboxs, with internal IP-Address. 2. the second solution is, using the current exchange server, which is installed on it exchange server 2000, but i will use the Publishing Roles in ISA server to puplish this server to out-side. i Prefear to work with the second solution , so can you give me your feedback regarding this solution. i am so sorry if i am explain too much information, but really i am trying to help me self, reading and read the resource kits of exchange & ISA server , and asking the expert here in this list. so , please accept my applogize for that. best reagrds,
