Subject: Re: RPM Packaging of the latest Snapshot
From: Michael Tokarev (mjttls.msk.ru)

The INSTALL.sh can be used to manually install things.
I used another one (inside .spec file).

Hers is my postfix.spec (that was sometime inherited from
those found at contrib.redhat.com, probably Bennet's one,
but it has no common parts with that today).

It is without chroot support, and it does NOT use chattr +S
on spool (that is BAD, but not for me, as I used it in
environment where power is relatively safe, and mail _can_
be lost (but never was), but speed is important -- excuse me
Wietse!) -- but this can easily be corrected.

Just to show an example... :)

%description
Postfix, see http://www.postfix.org, aims to be an alternative to the
widely-used sendmail program, which is responsible for 70 percent of
all e-mail delivered on the Internet.

Although IBM supported the Postfix development, it abstains from control
over its evolution. The goal is to have Postfix installed on as many
systems as possible. To this end, the software is given away with no
strings attached, so that it can evolve with input from and under control
of its users.

Be sure to read http://www.moongroup.com/postfix-faq/c22.html which covers
steps which should be taken prior to and after the installation of Postfix.
