Severity set to high, just 'cause it's a legal requirement....
As far as I can tell, the Postfix license (aka "IBM PUBLIC LICENSE -
SECURE MAILER") is not included anywhere in the postfix RPMs. The
license seems to require that a copy be included with the application,
and the man pages all say things like:
The Secure Mailer license must be distributed with this software.
To fix, just put the LICENSE file in %doc
I noticed it was missing as well. Its in the rpm as of
postfix-2.0.16-5, but its in /etc/postfix, not %doc
