hi Len,
Thanks for the reply.

will a dual P3-800 & above do?
Memory - 512MB ??
btw, can iMail be run behind a firewall
on a "fake" IP address? (of course, there
is a "real" IP mapped to this fake IP at
the firewall level).
some mail servers such as Mailmax cannot
do that.

Any option to move it out of the registry?
I'm worried that 10-20,000 domains or more will
overwhelm the registry size.

okd, has anyone tried Interbase?

they offer a MSSQL version. Problem is that even
their Access one has problems, such as you configure
a user, but the email never reach some users all
the time.

the do write to local file system, but they store
a reference of it (kind of Table of Contents) in
the MDB. Adding/deleting the table of contents
make MDB bloated.

I don't need it for other reasons.
Is iMail interbase d/b efficient?
Can I use CGI to talk to this internal database
(add/edit/delete users+domains)?
Are there any sample scripts out there?
Can someone kindly point me to a URL? - I'm
new on this list.

ok, thanks. will appreciate a URL.

Has someone done anything like a fileserver backend
with a few iMail servers fronting it? Is it possible
at all with iMail? something like Communigate Pro.
Thanks!
