no, use an old machine for IMGate, a P200 is fine. Many IMGate's run with less. Build two for mx1 and mx1, still no $ spent. >which is not really cogent and may not be within budget at >this point hmm, you make up the your straw-man problems and solve them, the rest of will fix the real problems :)) >Protecting the faculty from abuse of the student server >(and vice versa) is something that can be done with the current >hardware. The only real protection is internal firewalling. Back on-topic with IMGate as a solution to his problem.. :)) He runs two mail servers as independent mail domains, Imail as students.school.com and Exchange as faculty.school.com. Internal mail is with addresses like : [EMAIL PROTECTED] [EMAIL PROTECTED] and [EMAIL PROTECTED] [EMAIL PROTECTED] So the two servers remain totally and completely independent. No need to screw around with forwarding, aliases, and other error-prone make-work BS, goofy MX records, Imail forwarding, etc, etc. Internal mail routing could be via DNS resolution, or in each machine's hosts file ip.ad.re.s1 faculty.school.com ip.ad.re.s2 students.school.com To make it easy for the Real World, all the school's public addresses are simply [EMAIL PROTECTED] IMGate does all its usual stuff, and one additional little lookup file that re-writes internal addreses <==> external addresss. the file contains: [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] But if some external mail arrives at Imgate with the 3rd, sub-domain label, IMgate can handle, too, and relay it to the right internal mail server. The email address translation works both ways, both in and out through Imail. Both mail servers are taken off Internet. BIG PLUS No $ for new machines. Fantastically better anti-mail-abuse as a freebie, AND they will realize later that IMGate will turn out to be, retrospectively, the biggest benefit of this project. :)) Len Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
