[IMail Forum] Big project / Multiple Domains

[Bill Pierson]

Greetings all.   I'd like to get some opinions as to the best way to configure a server for multiple domains.   A client requested this and I'm trying to figure out the best way to implement it now, because in 2-3 weeks there could potentially be over 10 thousand users.   There are 6 domains that he would like the user to choose from when signing up. He only wants the user to have 1 account on the machine, period.   I was thinking that the most effective way of doing this would be to create one host, and alias all the rest, so that no matter what they signed up as, all E-Mail addresses would work, however only 1 mailbox would exist. (The user wouldn't explicitly be told that all domains work.....)   The machine is an Athlon 900 with 512MB's RAM, 30GB ATA/100 Hard drive (I-Mail has a 24GB compressed partition all for itself), Windows NT Server 4.0, Killerwebmail templates, EZSignup Utility.   Have any of you dealt with this issue?   Any/all suggestions would be appreciated. Thanks, --Bill
