I have a home server on a G3 powermac, and some of the PHP pages use the standard built in postfix to send email. I turned on Postfix by using the 3rd party app Post Fix Enabler. When I upgraded the system to 10.3.6, the following morning I found my computers HD grinding away like mad. I finally figured out that it was post fix causing the HD to go nuts, constantly read / writing data. My question is, how do I fix this? Right now I have post fix OFF, and while email doesn’t work, the HD isn’t grinding away anymore, everything else works fine. My server is at server.livermoronfilms.com if you’re curious.
