They don't necessarily have to be the ip's of any of your mailservers.
It's just exim telling you it queued a message it received, either from
localhost, or remote host, because it found out the load on your machine
is high, and it wants to save resources.
But I also see you use 'amavis' the virus scanner. And with high loads
of emails, amavis could well be the 'culprit' in causing high load on
your system.
> I just wonder how come other ip appear in my exim log file.
Because other IP's deliver mail to your mailserver, aparently.

Maybe someone is doing a spamrun on (one of?) your domain(s).
Then you'll receive a high volume of email in a short time.
Seeing that you use amavis to scan the email, my thought are that
amavis causes the high load, and exim stops delivering messages due to
that.

Read the documentation. It's well documented on how to deny connections
from certain (ranges of) ip's. I'm not here to configure your exim, am I?

See above. Read the documentation on
www.exim.org. There's a lot of
useful settings.

What you need to do is find out why the load on your machine is so high.
See what causes the load, with top(1) or ps(1). Then try to fix that.
If indeed it is amavis, or spamassassin, try to tome them down, try
disabling them for a couple of hours, see what happens.
You need to 'investigate' your system, instead of hoping I will fix it. :)
