Thanks to Steve who commented on the update notification we quikly discovered that the update cripples postfix just like it did with 10.5.5.
The update replaces the postfix binary (so there is no more support for mysql) and changes the configuration file main.cf so that postfix no longer accepts any connection from the outside world.
To solve these issues follow this procedure:
In the file /etc/postifx/main.cf comment out or delete the following line:
To solve the problem of the replaced binary you need to go nto the postfix source directoy of the last succesfull build and run:
Restarted postfix again and all was fine and running again.
Sorry, I’m still looking into the issue of missing this on my test system. I’ve upgraded my production system this morning before going into the office to make sure this was the case and how to solve it. My apologies for any inconviniences this might have caused.

Yep, bit me again, but it got fixed by the described fix.
Could we change the location that we install postfix to prevent it from stomping on our compiled version?

Michael, I understand your problem but doing that would make the setup more complicated. There are more dependancies then for instance with Apache.
Next time, before you update, check this site. I’m doing my best to test the updates as much and as soon as is possible. To keep you and all the others from messing up
