I’ve installed the updates on all my test machines running Snow Leopard 10.6.4 and Leopard 10.5.8 and I’ve noticed the following problems:

on Leopard

On Leopard there are the small known issues with postfix, replacing our binary and shutting don remote conntections. To correct it perform the following steps after the updates:

Re-install postfix by going into your latest source directory you’ve used the last time and run

sudo make install

Next, comment out or delete the following line from ‘/etc/postfix/main.cf‘:

inet_interfaces = localhost

Restart postfix (reloading config does not work) with:

sudo postfix stop

Postfix should restart automatically (if not run sudo postfix start).

Snow Leopard

Can’t detect any postfix problems on Snow Leopard. If you can confirm this please leave a comment.

To read more on the updates read the Apple Knowledge Base article on this update.

PS. Yes I know, I’m working on relocating postfix to another location so it won’t happen again. But lack of time is hampering progress….
