## Building RPMs

Starting with version 0.99, it is possible to build binary RPMs directly from the source tarball, so there's no longer a need to provide a separate set of source and binary RPMs. You will need RPM 3.0 or higher in order to build a binary RPM. Execute the following command:

       rpm -ta maildrop-3.2.1.tar.bz2

The binary RPM will be built with a customized configuration (userdb, GDBM, and quota enhancements enabled). Afterwards, simply execute `rpm -i` to install it. That's it.

With RPM 4.1 (Red Hat 8.0) use the 'rpmbuild' command instead of rpm: `rpmbuild -ta maildrop-3.2.1.tar.bz2`

If you would like to change the RPM build options, move `maildrop-3.2.1.tar.gz` to your `SOURCES` directory, extract the file `maildrop.spec`, move it to your `SPECS` directory, customize it if necessary, then build from the spec file.

maildrop includes documentation in HTML, as well as traditional man pages. The HTML versions may also be found at `https://www.courier-mta.org/maildrop/maildrop.html.`

## Installation

See `INSTALL` for installation information. If you are using an RPM-based Linux distribution, you can install build a binary RPM directly from the source code.

## Using maildrop with sendmail

Maildrop can be easily used as sendmail's local delivery agent, instead of procmail. Here is the suggested entry for sendmail.cf, courtesy of Eric J. Schwertfeger <ejs`@`bfd.com>:

    Mlocal,         P=/usr/local/bin/maildrop, F=lsAw5:/|@SPfhn, S=10/30, R=20/40,
                    T=DNS/RFC822/X-Unix,
                    A=maildrop -d $u

You may also consider including the D, F, and M flags as well.
