On the client side:
mv /var/qmail/bin/qmail-queue /var/qmail/bin/qmail-queue.orig
ln -s /var/qmail/bin/qmail-qmqpc /var/qmail/bin/qmail-queue
cat > /var/qmail/control/qmqpservers << EOF

On the server side:
- edit /etc/services and add the line
qmqp 628/tcp mail
- run qmail-qmqpd from inetd (not recommended). Edit
/etc/inetd.conf (all on one line)
qmqp stream tcp nowait qmaild /pkgs/bin/tcpd
/var/qmail/bin/tcp-env /var/qmail/bin/qmail-qmqpd
/pkgs/bin/tcpd is wherever you have tcp_wrappers installed.
Access control is handled by /etc/hosts.allow and
/etc/hosts.deny. tcp-env provides the necessary environment
variables to qmail-qmqpd.
- run qmail-qmqpd from tcpsever (highly recommended). In a startup
script run the following
tcpserver -u 7791 -g 2108 -c 40 -v -R -x \
/etc/qmqpdrules.cdb 0 qmqp /var/qmail/bin/qmail-qmqpd 2>&1 \
| accustamp | cyclog -s 1000000 /var/log/qmqp
7791 and 2108 are the uid and gid of the qmaild user and nofiles
group. tcpserver provides the necessary environment variables to
qmail-qmqpd. The -R option stops tcpserver doing identd lookups.
Access control is handled by the cdb file /etc/qmqpdrules.cdb.
This file is generated from /etc/qmqpdrules by running the
command
tcprules /etc/qmqpdrules.cdb /etc/qmqpdrules.tmp < /etc/qmqpdrules
You should also look at wrapping the tcpserver invocation in
supervise (part of Dan's daemontools package)
eval "env - PATH=$PATH supervise -r /etc/qmqpd \
tcpserver -u 7791 -g 2108 -c 40 -v -R -x \
/etc/qmqpdrules.cdb 0 qmqp /var/qmail/bin/qmail-qmqpd 2>&1 \
| accustamp | cyclog -s 1000000 /var/log/qmqp &"
This is how I run it at tansu.
