Rightfully (moving forward) I should rename this to OS X Things and remove the Mac.
Of course almost all of the posts really do refer to “Mac OS X Things”, so I should leave it alone.
There is a post about postfix getting stepped on.
There should be a post about the removal of /private/etc/apache2/users/* which sort of messed up my web serving since I actually included those files. Well, not me, the apache2 port in MacPorts caused them to be included.
I am back up and running pretty much completely in OS X (as opposed to Mac OS X) not server.
