New Code!
Postoffice has been pushed up to version 1.3.8c with the addition of MacOS 10 support, courtesy of my friend Andras Salamon, who deserted the Linux world a few years back for the seductive embrace of a version of Unix that's got a working user interface.
Other than OS_DARWIN support, there are no new features in this release, but it's still worth a new version of the code.
