That depends on the average size of each message and over what period of
time that quantity of messages are being delivered. That said, if you
put three 200GB SATA drives in a RAID5 array, add 2GB of RAM on a P4
with a 10Mbit/Sec. uplink, you can expect to be able to deliver 20,000
messages a day (although you might want to consider more bandwidth).
You should do what we did and just set up the server, and then write a
shell script to stress-test the box, and see what it can handle; how
much e-mail it can deal with. I wrote this script for FreeBSD to do
just that:
#!/bin/sh
#
# usage:
# ./stresstest.sh [EMAIL PROTECTED]
# or enter ./stresstest.sh by itself to be prompted for e-mail address.
mailaddr=$1
if /bin/test "$1" = ""
then
clear
echo -n "Please type the recipient's email address: "
read mailaddr
fi
echo Sending 1,000 32KB messages to $mailaddr...
#
for count in `jot 1000`
do
message=`jot -b 1 16384`
( /bin/echo "To: $mailaddr" ;\
/bin/echo "Subject: qmail toaster stress test" ;\
/bin/echo "$message" ;\
/bin/echo "." ;\
) | /usr/sbin/sendmail -t [EMAIL PROTECTED]
echo -n .
done
echo "Done!"
To delete the test messages, just go into qmailadmin and delete the
recipient mailboxes.
Jot doesn't come with linux, but you can install it by downloading it
from
http://ftp.debian.org/debian/pool/main/a/athena-jot/athena-jot_9.0.orig.
tar.gz
tar -zxvf athena-jot_9.0.orig.tar.gz
cd into the dir it creates, and follow the instructions on compiling it.
