This is not the way to go.
A mail server should *never* allow unauthenticated users to send mail. The most
reasonable way to do this is to require port 587 for all mail submission and
require secure authentication on that port. Do not allow users to use port 25
at all.
main.ct:
smtpd_sasl_auth_enable = no
master.cf:
submission inet n - n - - smtpd

-o smtpd_sasl_auth_enable=yes

Apple broke AppleScripting signatures in Mail.app, so no random signatures.
