Installing qmail under FreeBSD

# cd /usr/ports/mail/qmail
# make all install clean

Check the boxes for:

SMTP_AUTH_PATCH
QMAILQUEUE_PATCH
BIG_TODO_PATCH

Click OK. After installation, enable qmail by running the script:

# /var/qmail/scripts/enable-qmail

# cd /usr/ports/sysutils/ucspi-tcp
# make all install clean

Check the boxes for:

man
ssl

Click OK.

# cd /usr/ports/security/checkpassword
# make all install clean

Make the following change to the file /etc/manpath.config:

# echo "OPTIONAL_MANPATH /var/qmail/man" >> /etc/manpath.config

Then run:

# makewhatis

so that the manpages can be used immediately.

# echo "127.0.0.1:allow,RELAYCLIENT=\"\"" > /etc/tcp.smtp

At this point, if you have a LAN on which client machines will require access to the SMTP port to send email, add the network part of the LAN's IP address space. For example, if hosts on the LAN are in the range 192.168.0.1–192.168.0.254, issue this command:

# echo "192.168.0.:allow,RELAYCLIENT=\"\"" >> /etc/tcp.smtp

Finally, build the ruleset for tcpserver:

# echo :allow >> /etc/tcp.smtp
# /usr/local/bin/tcprules /etc/tcp.smtp.cdb /etc/tcp.smtp.tmp < /etc/tcp.smtp

Append the following lines to the end of /etc/rc.conf to set some variables used in the qmail startup script to follow:

# qmail options
qmail_smtp_enable="YES"
qmail_pop_enable="YES"
qmail_enable="YES"

In the following sections, HOSTNAME refers to the name of the localhost, and can be determined by running:

# hostname -s

HOSTNAME.DOMAIN refers to the machine's fully qualified domain name (FQDN), and can be determined with:

# hostname

Obviously, DOMAIN refers to the domain in which the machine resides, and is the FQDN minus the HOSTNAME part.

Create /var/qmail/rc:

#!/bin/sh

#
# This script starts and stops the qmail mail functions.
#

# Suck in the configuration variables.

Make the script executable:

chmod 750 /var/qmail/rc

qmail will not send email directly to root. Even if no one else is sending email to root, the system is probably sending its daily checks to root every night, so the barest minimum qmail setup requires an alias for root:

# echo EMAILADDRESS > /var/qmail/alias/.qmail-root

EMAILADDRESS is the real address to which you want root's mail sent. Alias files can contain multiple addresses, but each address must be on a separate line.

# killall sendmail
# rm /var/run/sendmail.pid

# /usr/local/etc/rc.d/qmail.sh start

# ps -ax | grep tcpserver
# ps -ax | grep qmail
