Yup. It's funny that this is the first thing one notices when moving
away from qmail. People who haven't used dot-qmail files think you
are crazy (see the postfix-users archives), but they just don't know
what they are missing.

Procmail is just like maildrop except less resource conscious, less
reliable, and with a more hideous syntax; if you can't do it with
maildrop, you won't be able to do it with procmail.

There is no drop in solution for dot-qmail support, but Ron Bickers
figured out a way to use qmail-local for local delivery on a Postfix
system. I'll attach his README:
$Id: QMAIL_LOCAL_README 26 2004-02-11 08:10:33Z rbickers $
Using qmail for Local Delivery
==============================
This document describes how to use qmail as a local delivery agent for
Postfix.
NOTE: This was designed as an aid in migrating from qmail to Postfix and from
qmail-dependent software to MTA independent software. It is not intended to
be a production quality qmail-compatible local delivery agent. It is assumed
that you are already familiar with qmail administration.
Setup qmail
===========
Install a stripped down version of qmail (similar to a mini-qmail[2]
installation) as follows. If you already have qmail installed, much of this
will already be done:
1) Install qmail in /var/qmail, including all the usual binaries in
/var/qmail/bin.
2) Add a symbolic link to qmail-qmqpc from /var/qmail/bin/qmail-queue.
3) Place 127.0.0.1 in /var/qmail/control/qmqpservers.
4) Setup /var/qmail/control/me, /var/qmail/control/defaultdomain, and
/var/qmail/control/plusdomain, so that qmail-inject uses appropriate
host names in outgoing mail.
5) Place hostname in /var/qmail/control/idhost, so that qmail-inject
generates Message-ID without any risk of collision.
You do NOT need to setup any long-running qmail processes. All messages sent
through qmail-inject or qmail-queue will be handed directly to Postfix via
QMQP.
Setup mailbox_command script
============================
Place the following in /usr/local/libexec/postqmail-local:
#!/bin/sh
export PATH=$PATH:/var/qmail/bin
tail +3 | seekablepipe qmail-local -- \
"$USER" "$HOME" "$LOCAL" "${EXTENSION:+-}" "$EXTENSION" "$DOMAIN" \
"$SENDER" ./Maildir/
e=$?
(($e == 111)) && exit 75
(($e == 100)) && exit 77
exit $e
You will either need 'tail' and 'seekablepipe' in the PATH, or adjust the
script to point directly to them.
A seekablepipe program is available as part of the conn-tools[1] product.
Or, you can use the following shell script, adjusting the tmp directory as
desired:
#!/bin/sh
set -e
tmp=/var/tmp/seekable.$$
exec 3<&0 4<&1 >$tmp <$tmp
rm $tmp
cat <&3
exec ${1+"$@"} 1<&4 3>&- 4>&-
Setup Postfix
=============
Setup the QMQP server in Postifx by adding (or uncommenting) the following
line in master.cf:
628 inet n - n - - qmqpd
Place the following in /etc/postfix/main.cf:
# qmail local delivery.
prepend_delivered_header = file, forward
mailbox_command_maps = hash:/etc/postfix/mailbox_commands
qmqpd_authorized_clients = 127.0.0.1
The prepend_delivered_header line removes the addition of the Delivered-To
header for commands. If Postfix adds this header, qmail-local will bounce
the message as looping. qmail-local will add its own Delivered-To header.
If you want Delivered-To headers added to commands for other reasons, you can
adjust postqmail-local to use 'tail +5' instead of 'tail +3', but you will
lose the X-Original-To header added by Postfix.
Place in /etc/postfix/mailbox_commands a mapping of usernames that will use
postqmail-local delivery. For example:
# These users need qmail-local delivery.
johndoe /usr/local/libexec/postqmail-local
janedoe /usr/local/libexec/postqmail-local
If you want all local delivery to use postqmail-local, you may replace
mailbox_command_maps with the following:
mailbox_command = /usr/local/libexec/postqmail-local
Notes
=====
* ezmlm should work WITHOUT the modifications described in QMQP_README.
