Hi John They're not ISP's, but mail hosting companies. I know of 2 companies here in Bermuda that use them, one's a large insurance company, (over 500 users here), with office's here, the Bahama's and Cayman, the other is a small office with 5 users, the 5 user office pays $39US a month for their mail hosting, don't know how much the insurance company pays The benefits are no hardware costs, no os/costs, no exchange cost, no upgrade costs, 24/7 365 days a year uptime guaranteed, full back up solution. Search on google, you'll find a few....:)) Steve -----Original Message----- From: Greg Mulholland [mailto:greg_mul@xxxxxxxxxxxxxxx] Sent: Thursday, March 06, 2003 1:22 AM To: Isa List Subject: [isalist] RE: client behind ISA access to remote Exchange behind another ISA using MAPI http://www.ISAserver.org Maybe im old fashioned but in that situation I would prefer to have the control over it myself. That way you could hopefully use it to its full potential And come to think of it I can recall people that do it, I just wouldn't prefer it.

I couldn't think of a real reason to use them in a corporate environment, which is what I think John was getting at. Maybe if money is an issue, but if it was then exchange is the wrong option I would think Greg -----Original Message----- From: Steve Moffat [mailto:steve@xxxxxxxxxxxxxxx] Sent: Thursday, March 06, 2003 12:01 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: client behind ISA access to remote Exchange behind another ISA using MAPI http://www.ISAserver.org Hi John H I would imagine, that if it's not a configuration with your isa server, then it's a problem with the isa server config at your mail hosting company. Hi John T, There are literally hundreds of outsourcing mail servers on the web that use exchange, and will host all your email services for a few dollars a month. Thenks!!

See my reply to 307926. In your case, is a site to site VPN possible? (It would have to be strictly regulated.) In my opinion, Exchange was never designed nor will it function properly to serve as a mail server for non-local domains. It is the Lexus of corporate e-mail servers. The key word is corporate. If you have to have Exchange and you have to outsource, I would seriously consider a on-site outsourced Exchange server, where it is in your office but is entirely taken care of by someone else. I have never heard of Exchange being used for a corporation where the Exchange server was not within that company. John Tolmachoff MCSE, CSSA IT Manager, Network Engineer RelianceSoft, Inc.
