ha ha, sucker!!! hey, just jokin!!
>1. Which is the better OS to run it on today NT4 SP6 or NT2000 ?
A toss up, both work ok, the vast majority of IMail is on NT4. Go with
whatever you're most comfortable with.
>2. What size of processor and memory is recommended to good web
> based interface performance ?
A P200 with 128 megs RAM and a few gigs of disk on NT4 SP6a workstation
would be comfortable with the users and domains you have now.
Without having MS IIS on the machine, you don't have to stop it or
uninstall it, so you can run Imail's web server on port 80 and have your
users check there at URL's like this:
webmail.myvirtualdomain.com
rather than
mail.myvirtualdomain.com:8383
>3. Which is better for virtual hosting all domain from one IP or
> a seperate IP for each domain ?
IP authorities like RIPE and ARIN are very strongly against one ip per
domain as they think it wastes ip space unnecessarily, and very strongly
for virutal web and mail servers behind single ip's.
If you only have one disk, partition it like this, suggested:
c: system
d: progs
put imail program here, under which goes the very busy Imail\spool directory
e: user1
directories for different virtual domains, and the users mailboxes,
also very busy.
f: user2
ditto
If you have two disks, put c: and d: on one, and e: and f: on the other.
Install all domains with name of domain.com and alias name of mail.domain.com.
Have fun.
