I know one other Imail system ("Jeff Madison" <[EMAIL PROTECTED]>) with 180K
users on a quad xeon / 2 gb RAM. His machine is eaten up with iwebmsg and
pop3d. But he didn't say he had stopping problems.

yep, but I suspect that iwebmsg and SMTP AUTH are unstable under heavy
load, from scattered reports here.

I haven't heard of a limit.

All I can suggest is to lighten the load on the Imail machine by adding
IMGate out front
(
fewer SMTP and SMTPD processes,
existing in memory for shorter times,
absence of DNS lookups,
reduction abuse and spam (maybe 20 to 40% messages rejected before they
arrive at IMail)
moving all outgoing queuing from Imail
protection from DoS attacks such as harvesting and mail bombs
)
This would leave a less busy machine, more available for iwebmsg. But I
cannot guarantee it would fix the problem, but it would certainly move you
in the right direction of reducing the load on the Imail machine.
I guess you have all the latest MS service packs??
