Qmail is a Mail Transfer Agent. It handles incoming and outgoing mail. Install qmail if you want your OpenACS server to send and receive mail, and you don't want to use an alternate MTA.
Red Hat 9: all djb tools (qmail, daemontools, ucspi) will fail to compile in Red Hat 9 because of changes to glibc (patches)
Install ucspi. This program handles incoming tcp connections. Download ucspi and install it.
[root root]#cd /usr/local/src
[root src]#wget http://cr.yp.to/ucspi-tcp/ucspi-tcp-0.88.tar.gz
[root src]#tar xzf ucspi-tcp-0.88.tar.gz
cd /usr/local/src wget http://cr.yp.to/ucspi-tcp/ucspi-tcp-0.88.tar.gz tar xzf ucspi-tcp-0.88.tar.gz
Red Hat 9 only
wget http://moni.csi.hu/pub/glibc-2.3.1/ucspi-tcp-0.88.errno.patch
cd ucspi-tcp-0.88
patch -p1 <../ucspi-tcp-0.88.errno.patch
cd ..
All platforms continue:
[root src]#cd ucspi-tcp-0.88
[root 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 ucspi-tcp-0.88]#make setup check
./install ./instcheck [root ucspi-tcp-0.88]# 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 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 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.

Replace sendmail with qmail's wrapper.
[root qmail-1.03]#rm -f /usr/bin/sendmail /usr/sbin/sendmail
[root qmail-1.03]#ln -s /var/qmail/bin/sendmail /usr/sbin/sendmail
[root qmail-1.03]# rm -f /usr/bin/sendmail /usr/sbin/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 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 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 qmail-1.03]#cd ~alias; touch .qmail-postmaster .qmail-mailer-daemon .qmail-root
[root alias]#chmod 644 ~alias/.qmail*
[root alias]#/var/qmail/bin/maildirmake ~alias/Maildir/
[root alias]#chown -R alias.nofiles /var/qmail/alias/Maildir
[root 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 alias]#echo "./Maildir" > /var/qmail/bin/.qmail
[root alias]#cp /tmp/openacs-5.2.0/packages/acs-core-docs/www/files/qmail.rc.txt /var/qmail/rc
[root alias]#chmod 755 /var/qmail/rc
[root alias]# echo "./Maildir" > /var/qmail/bin/.qmail cp /tmp/openacs-5.2.0/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 root]#/var/qmail/bin/maildirmake /etc/skel/Maildir
[root root]#echo "./Maildir/" > /etc/skel/.qmail
[root root]# /var/qmail/bin/maildirmake /etc/skel/Maildir echo "./Maildir/" > /etc/skel/.qmail
As recommended, we will run qmail with daemontools control files. Create daemontools control directories, set up a daemontools control script, copy the supervise control files, and set permissions. The last line links the control directories to /service, which will cause supervise to detect them and execute the run files, causing qmail to start.

Wait ten seconds or so, and then verify that that the four qmail processes are running. If uptimes don't rise above 1 second, this may indicate broken scripts that are continuously restarting. In that case, start debugging by checking permissions.
[root root]# qmailctl stat
/service/qmail-send: up (pid 32700) 430 seconds
/service/qmail-send/log: up (pid 32701) 430 seconds
/service/qmail-smtpd: up (pid 32704) 430 seconds
/service/qmail-smtpd/log: up (pid 32705) 430 seconds
messages in queue: 0
messages in queue but not yet preprocessed: 0
[root root]#
Further verify by sending and receiving email. Incoming mail for root is stored in /var/qmail/alias/Maildir
.
