Hi. I needed maildrop for a client, so I packaged it;
it's already in master's incoming. Here's the Readme:
maildrop - mail delivery agent with filtering abilities
Current version is 0.54a

Where to find maildrop
The HTML version of the maildrop README is located at
. Although the following files may also be found there, please check
your favorite archive for any local copies:
maildrop-0.54a.tar.gz - the source code tarball.
maildrop-0.54a-1.src.rpm - the distribution source code in the RPM
format. To build a binary RPM run the command rpm --rebuild
maildrop-0.54a-1.i386.rpm - prebuilt binary RPM for Red Hat 5.1 i386.
The RPMs are signed with my PGP key:
maildrop includes documention in HTML, as well as traditional man
pages. The HTML versions may also be found at
maildrop is a replacement for your local mail delivery agent. maildrop
reads a mail message from standard input, then delivers the message to
your mailbox. maildrop knows how to deliver mail to mbox-style
mailboxes, and maildirs. "maildir" is a mailbox format used by the
maildrop can optionally read instructions from a file on how to filter
incoming mail, and, based upon the instructions, deliver mail to
alternate mailboxes, or forward it to somewhere else, like procmail.
Unlike procmail, maildrop uses a structured filtering language that's
a bit easier on the eyes.
maildrop is written in C++, and is significantly larger than procmail,
in compiled form. However, it uses resources much more efficiently.
Unlike procmail, maildrop will not read a 10 megabyte mail message
into memory. Large messages are saved in a temporary file, and are
filtered from that file. Files are saved in the user's home directory.
If the standard input to maildrop is a file, not a pipe, no temporary
file will be necessary.
maildrop performs syntax checks on the filter file before attempting
to deliver a message. Unlike procmail, if the filter file contains
syntax errors, maildrop will terminate without delivering the message,
allowing the user to fix the typo, and try again later without losing
maildrop uses the GNU autoconf configure script.
See the file INSTALL for installation information. If you are using an
RPM-based Linux distribution, you can install the binary RPM (see
above), or rebuild the source RPM, normally.
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,

You may also consider including the D, F, and M flags as well.
* V0.54a - miscellaneous fixes. Default SHELL to /bin/sh if the
shell is not specified in /etc/passwd. FreeBSD does not support
lockf() on /dev/null - lockf() will not cause a fatal error if it
fails on a character or a block special file. Fixed bug in
configure script regarding failed initialization of
* V0.54 - edited the documentation. Added support for VPATH builds
using automake - suggested by Harlan Stenn
<Harlan.Stenn@pfcs.com>. Major rework of the configuration code.
Changed all #define-s in config.h to use the configure script.
* V0.51c - Fixed the subtraction operator bug. Added sendmail
* V0.51b - Fixed compilation error for BSD. Fixed spurious "invalid
directory permission" error if $HOME/.mailfilters does not exist
in special embedded mode - maildrop will simply indicate quiet
