Jim,
Oppth .... there is a typo in this .... the INTNETADR parameter should
read 10.1.1.1 to match the stated example.
See what happens when I rush and don't proof read?
:-)

To prevent this from happening in the first place, you'll need to
restrict
SMTP relaying. Use the CHGSMTPA command to change the allow relay
setting
from *ALL to *LIST. Then, create an accept entry for your AS400
using the
ADDSMTPLE command. For example, if the IP address of your system is
10.1.1.1, then run the command:
ADDSMTPLE TYPE(*ACCEPT) INTNETADR('10.1.1.2')
SUBNETMASK('255.255.255.255')
This will allow your AS400 to send mail, but nobody else. Once this
has
been set up, end the SMTP server and restart it.
If high activity continues, then end the SMTP server again and run
the
following command:
CRTDTAARA DTAARA(QUSRSYS/QTMSCLEAN) TYPE(*CHAR) LEN(1)
VALUE('C') AUT(*ALL)
Then, start your SMTP server one more time. At this point, any
pending
messages that the server was continuing to try and send will be
cancelled.

Rich,
I shut down the smtp server, and the usage drops as you state. How
do I
determine what is using it and fix or restrict it? Right now I am
running
at .4 as compared to about 64. When I restart it, it goes back to
high
usage.

I agree with others that a spammer has commandeered your server and
is
relaying
mail through it. You won't see any mail traffic locally, but the
high
utilization in these jobs is a clear indicator. I've had this
happen to
me.
You can proove it by shutting down SMTP (command: ENDTCPSVR *SMTP)
for
a
little while and see if the problem goes away. If this is it, then
you
will
have to reconfigure SMTP on your system to only allow limited
relaying.
