I have looked at both Liaison and GatorMail-M as a mechanism for merging two Microsoft Mail systems without compromising security. You can use either one. With Liaison, you must purchase the "Liaison Gateway for Microsoft Mail. This is a special version of Liaison that handled MS Mail. You should also use Version 2.0B of Microsoft Mail Server, but version 2.0A might also work fine. The security is specified by the Macintosh making the Liaison connection. The machine being called cannot limit security. You log on to the mail server as Network Manager, and in the special server configuration in the mail menu, you specify you want traffic to be Microsoft Mail only. The machine being called doesn't need the Liaison MS Mail Gateway, just regular Liaison. Some things to be aware of: The Macintosh with Liaison and a Modem (or dedicated line) is the "bridge". When you have several mail servers, you must install the Liaison "network tuner" on each server, so it knows about the other mail servers. The network tuner INIT prevents slow networks from timing out. The first connection will take some time as all MS Mail names are propagated. All mail names from all mail servers will be seen by all users. If you have more than 16 mail servers, you must wait for the next release of Liaison, which is due Real Soon Now. Another solution is to use two copies of GatorMail-M, from Cayman. You can put a Unix machine between the two, or route SMTP mail from one Mac to another using TCP/IP routing. This keeps the networks and mail names 100% separate. This is a more expensive solution. I have not been able to get Liaison Gateway and GatorMail-M gateway on the same Mail Server. They don't like each other. -- Bruce G. Barnett barnett@crd.ge.com uunet!crdgw1!barnett
