[Cialug] Postfix issue

[Tony Bibbs]

Got an issue where undue strain is being put on my server by postfix. 
When it isn't running the load is around .27 but when it is running it's 
up to near 5 at times.  I'm pouring through the logs and the first thing 
I notice is a *ton* of these sorts of entries:

May 22 09:17:14 iowaoutdoors postfix/smtp[15805]: 192922CD35B: 
to=<luna_pi@click21.com.br>, relay=mail3.click21.com.br[200.255.27.137], 
delay=391139, status=sent (250 Ok: queued as 6D160AB60C)

They happen one right after another just a few seconds apart.  I'm not a 
mail server admin (which is my problem, I'm sure) but what does this mean?
