Before you do the build, make sure you run niscript (as root) to properly
create a postfix user, and postfix & maildrop groups.
DO NOT USE THE MULTIPLE USERS APPLICATION TO CREATE THE POSTFIX USER!
1) su
2) ./niscript
this creates the necessary users & groups for proper operation
of postfix
3) ./stash-sendmail
move your existing sendmail binaries somewhere safe
4) make install
When the script asks you for setgid (the default will be no) tell it
maildrop
5) edit /etc/postfix/main.cf to suit your requirements
6) postfix start
7) Test. Read INSTALL for a series of suggested tests.
8) cp -R darwin-Postfix /System/Library/StartupItems/Postfix
9) edit /System/Library/StartupItems/Sendmail. add "exit 0" as the
first line
