Install ucspi. This program handles incoming tcp connections. Download ucspi and install it.

[root@yourserver root]# cd /usr/local/src
[root@yourserver src]# tar xzf /tmp/ucspi-tcp-0.88.tar.gz
[root@yourserver src]# cd ucspi-tcp-0.88
[root@yourserver ucspi-tcp-0.88]# make
( cat warn-auto.sh; \
echo 'main="$1"; shift'; \
(many lines omitted)
./compile instcheck.c
./load instcheck hier.o auto_home.o unix.a byte.a
[root@yourserver ucspi-tcp-0.88]# make setup check
./install
./instcheck
[root@yourserver ucspi-tcp-0.88]#
cd /usr/local/src 
tar xzf /tmp/ucspi-tcp-0.88.tar.gz 
cd ucspi-tcp-0.88 
make 
make setup check

Verify that ucspi-tcp was installed successfully by running the tcpserver program which is part of ucspi-tcp:

[root@yourserver ucspi-tcp-0.88]# tcpserver
tcpserver: usage: tcpserver [ -1UXpPhHrRoOdDqQv ] [ -c limit ] [ -x rules.cdb ] [ -B banner ] [ -g gid ] [ -u uid
] [ -b backlog ] [ -l localname ] [ -t timeout ] host port program
[root@yourserver ucspi-tcp-0.88]#

(I'm not sure if this next step is 100% necessary, but when I skip it I get problems. If you get the error 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1) then you need to do this.) AOLServer sends outgoing mail via the ns_sendmail command, which pipes a command to the sendmail executable. Or, in our case, the qmail replacement wrapper for the sendmail executable. In some cases, though, the outgoing mail requset is apparently sent through tcp/ip, so that it comes to qmail from 127.0.0.1 (a special IP address that means the local machine - the "loopback" interface). Unless this mail is addressed to the same machine, qmail thinks that it's an attempt to relay mail, and rejects it. So these two commands set up an exception so that any mail sent from 127.0.0.1 is allowed to send outgoing mail.

[root@yourserver ucspi-tcp-0.88]# cp /tmp/openacs-5.0.0/packages/acs-core-docs/www/files/tcp.smtp.txt /etc/tcp.smtp

Install Qmail. 

Download qmail, set up the standard supporting users and build the binaries:

(If you are using Red Hat 9.0, you need to put #include <errno.h> as the first line of /usr/local/src/qmail-1.03/error.h. More information)

[root@yourserver root]# cd /usr/local/src
[root@yourserver src]# tar xzf /tmp/qmail-1.03.tar.gz

Replace sendmail with qmail's wrapper.

[root@yourserver qmail-1.03]# rm -f /usr/bin/sendmail
[root@yourserver qmail-1.03]# ln -s /var/qmail/bin/sendmail /usr/sbin/sendmail
[root@yourserver qmail-1.03]#
rm -f /usr/bin/sendmail 
ln -s /var/qmail/bin/sendmail /usr/sbin/sendmail

Configure qmail - specifically, run the config script to set up files in /var/qmail/control specifying the computer's identity and which addresses it should accept mail for. This command will automatically set up qmail correctly if you have correctly set a valid host nome. If not, you'll want to read /var/qmail/doc/INSTALL.ctl to find out how to configure qmail.

[root@yourserver qmail-1.03]# ./config-fast yourserver.test
Your fully qualified host name is yourserver.test.
Putting yourserver.test into control/me...
Putting yourserver.test into control/defaultdomain...
Putting yourserver.test into control/plusdomain...
Putting yourserver.test into control/locals...
Putting yourserver.test into control/rcpthosts...
Now qmail will refuse to accept SMTP messages except to yourserver.test.
Make sure to change rcpthosts if you add hosts to locals or virtualdomains!
[root@yourserver qmail-1.03]#
./config-fast yourserver.test

All incoming mail that isn't for a specific user is handled by the alias user. This includes all root mail. These commands prepare the alias user to receive mail.

[root@yourserver qmail-1.03]# cd ~alias; touch .qmail-postmaster .qmail-mailer-daemon .qmail-root
[root@yourserver alias]# chmod 644 ~alias/.qmail*
[root@yourserver alias]# /var/qmail/bin/maildirmake ~alias/Maildir/
[root@yourserver alias]# chown -R alias.nofiles /var/qmail/alias/Maildir
[root@yourserver alias]#
cd ~alias; touch .qmail-postmaster .qmail-mailer-daemon .qmail-root 
chmod 644 ~alias/.qmail* 
/var/qmail/bin/maildirmake ~alias/Maildir/ 
chown -R alias.nofiles /var/qmail/alias/Maildir

Configure qmail to use the Maildir delivery format (instead of mbox), and install a version of the qmail startup script modified to use Maildir.

[root@yourserver alias]# echo "./Maildir" > /var/qmail/bin/.qmail
[root@yourserver alias]# cp /tmp/openacs-5.0.0/packages/acs-core-docs/www/files/qmail.rc.txt /var/qmail/rc
[root@yourserver alias]# chmod 755 /var/qmail/rc
[root@yourserver alias]# 
echo "./Maildir" > /var/qmail/bin/.qmail 
cp /tmp/openacs-5.0.0/packages/acs-core-docs/www/files/qmail.rc.txt /var/qmail/rc 
chmod 755 /var/qmail/rc 

Set up the skeleton directory so that new users will be configured for qmail.

[root@localhost root]# /var/qmail/bin/maildirmake /etc/skel/Maildir
[root@localhost root]# echo "./Maildir/" > /etc/skel/.qmail
[root@localhost root]# 
/var/qmail/bin/maildirmake /etc/skel/Maildir
echo "./Maildir/" > /etc/skel/.qmail

Qmail runs in two parts. First, several different qmail daemons are started by the qmail rc file. Second, a process is started in within tcpserver to listen for incoming smtp traffic. Run both of these commands to start qmail. Be very careful about line breaks - there should be a total of two commands here. Note also that the tcpserver command takes the uid and guid of qmaild, which will only be 502 and 501 if you have followed all of these instructions exactly and in order. Otherwise, grep qmaild /etc/passwd to find uid and guid, in that order.

[root@yourserver alias]# /usr/local/bin/tcpserver -x /etc/tcp.smtp.cdb -v -u 502 -g 501 0 smtp /var/qmail/bin/qmail-smtpd 2>&1 | /var/qmail/bin/splogger smtpd 3 &
[1] 15863
[root@yourserver alias]# csh -cf '/var/qmail/rc &'
[1] 15865
[root@yourserver alias]#
/usr/local/bin/tcpserver -x /etc/tcp.smtp.cdb -v -u 502 -g 501 0 smtp /var/qmail/bin/qmail-smtpd 2>&1 | /var/qmail/bin/splogger smtpd 3 & 
csh -cf '/var/qmail/rc &'

Verify that seven different qmail threads are running:

[root@yourserver alias]# ps -auxw | grep
          qmail

[root@yourserver alias]#

Further verify by sending and receiving email. Incoming mail for root is stored in /var/qmail/alias/Maildir. If it worked, make it permanent by putting the same commands in your startup scripts. (These instructions put the commands in rc.local, which means that they'll be run once, on boot. There will be no monitoring and no interface to start and stop and check status. We ought instead to either use full init scripts or daemontools.)

[root@yourserver alias]# echo "/usr/local/bin/tcpserver -x /etc/tcp.smtp.cdb -v -u 502 -g 501 0 smtp /var/qmail/bin/qmail-smtpd \ " >> /etc/rc.local
[root@yourserver alias]# echo "2>&1 | /var/qmail/bin/splogger smtpd 3 &  " >> /etc/rc.local
[root@yourserver alias]# echo "csh -cf '/var/qmail/rc &' " >> /etc/rc.local
[root@yourserver alias]# 
echo "/usr/local/bin/tcpserver -x /etc/tcp.smtp.cdb -v -u 502 -g 501 0 smtp /var/qmail/bin/qmail-smtpd \ " >> /etc/rc.local
