Download qmail source code.

cd /usr/local/srcwget http://cr.yp.to/software/qmail-1.03.tar.gz

Download patches.

wget http://tomclegg.net/software/patch-qmail-103.patchwget http://tomclegg.net/software/patch-qmail-sendmail-flagf.patchwget http://tomclegg.net/software/patch-qmail-badmailfrom-wildcardwget http://tomclegg.net/software/patch-qmail-capa-pop3dwget http://tomclegg.net/software/patch-qmail-capa-popupwget http://tomclegg.net/software/patch-qmail-remote-authwget http://tomclegg.net/software/patch-qmail-smtpd-authwget http://tomclegg.net/software/patch-qmail-smtpd-auth-logExtract qmail and apply patches.

tar xzf qmail-1.03.tar.gzcd qmail-1.03for d in ../patch-qmail-*; do patch <“$d”; doneCompile and install qmail.

make setup check

Some linux systems don’t like the way qmail uses “errno”:

./load auto-str substdio.a error.a str.asubstdio.a(substdo.o)(.text+0x43): In function `allwrite’:: undefined reference to `errno’collect2: ld returned 1 exit statusmake: *** [auto-str] Error 1

To fix this, edit the error.h file in the qmail source code. Add this after 2, before the line saying “extern int errno;”:

#include “errno.h”

After you add that, do “make setup check” again.

You will need to do this again in a few minutes, when you compile checkpassword and daemontools.

Configure qmail.

cd /var/qmail/controlhostname >mecp me localsecho YOUR.IP.ADDR.HERE >>localscp locals rcpthosts

cd /var/qmail/aliasecho YOUR@EMAIL.ADDRESS >.qmail-rootcp .qmail-{root,mailer-daemon}cp .qmail-{root,postmaster}cp .qmail-{root,hostmaster}cp .qmail-{root,abuse}Download and install checkpassword.

Add to /etc/profile:

ln -s /var/service/qmail-send /service/

Wait a few seconds. qmail-send should be running now. pstree should show something like this.

Switching mail service from sendmail to qmail

Translate /home/*/.forward to /home/*/.qmail (details omitted).

Translate /etc/mail/virtusertable to /var/qmail/alias/.qmail-* and /var/qmail/control/virtualdomains (details omitted).

Test local delivery using “telnet localhost 2525”

Test remote delivery using “telnet localhost 2525”

Test relay control using “telnet YOUR.IP.ADDR.HERE 2525” from somewhere else. You should be able to connect, but mail to test@example.com should be refused.

Test pop using “telnet localhost 25110”

Replace /usr/sbin/sendmail with a symlink to /var/qmail/bin/sendmail

cd /usr/sbinmv -i sendmail sendmail~ln -s /var/qmail/bin/sendmail

Turn off pop3 service in /etc/xinetd.d/ipop3 and kick xinetd.

perl -pi~ -e ‘s,^},tdisable = yesn},’ /etc/xinetd.d/ipop3killall -USR1 xinetd

Make sure sendmail won’t start at boot time any more.

Stop sendmail.

killall sendmail

Change port 2525 to port 25 in /service/qmail-smtpd/run, change port 25110 to port 110 in /service/qmail-pop3d/run, and restart qmail-smtpd.

svc -t /service/qmail-smtpd /service/qmail-pop3d

Convert /var/spool/mail/* to /home/*/Maildir/ (details omitted).

If you use pine, change the inbox-path in your ~/.pinerc file:

inbox-path={localhost/pop3}INBOX
