Configure Qmail

Copy the script to its proper locations

cp /downloads/scripts/qmailctl /var/qmail/bin/qmailctl (View the script qmailctl)

Adapt script permission

chmod 755 /var/qmail/bin/qmailctl

The script /var/qmail/rc (View here) is no longer used.

In original qmailrocks installation guide, it was used in script send_run replaced by service-send-run (from John M.Simpson) in this guide.

Create needed symlinks

ln -s /var/qmail/bin/qmailctl /usr/bin

Set Maildir as default mailbox type (./Mailbox for mbox type)

echo ./Maildir > /var/qmail/control/defaultdelivery

Set some configuration (You can find more on http://www.lifewithqmail.com/lwq.html#configuration)

echo 255 > /var/qmail/control/concurrencyremote
echo 30 > /var/qmail/control/concurrencyincoming
echo 3 > /var/qmail/control/spfbehavior
echo postmaster > /var/qmail/control/bouncefrom
echo yourdomain.tld > /var/qmail/control/doublebouncehost
echo postmaster > /var/qmail/control/doublebounceto
echo 'MEDIUM:HIGH:!SSLv2:!MD5:!RC4:!3DES' > /var/qmail/control/tlsserverciphers

cd /var/qmail/control/
chmod 644 bouncefrom doublebouncehost doublebounceto concurrencyremote concurrencyincoming spfbehavior tlsserverciphers

Set maximum message size to be 8Mb

echo '8000000' > /var/qmail/control/databytes

Set 30 seconds as timeout

echo 30 > /var/qmail/control/timeoutsmtpd

Allows localhost to send mails

echo '127.:allow,RELAYCLIENT=""' >> /etc/tcp.smtp
qmailctl cdb

If you use backup MX servers or if this server is acting as smart host for others, I advice you to add execute command :

echo 'OTHER-SERVER-IP:allow,RELAYCLIENT="",QS_SPAMASSASSIN="1"' >> /etc/tcp.smtp
qmailctl cdb

If you want to learn other available options, take a look on this sample.

Create mail aliases

echo some_address > /var/qmail/alias/.qmail-root
echo some_address > /var/qmail/alias/.qmail-postmaster
echo some_address > /var/qmail/alias/.qmail-mailer-daemon

Where some_address is the system user or email address you want these addresses aliased to

chmod 644 /var/qmail/alias/.qmail*

cd /usr/src/qmail/qmail-1.03
./config-fast host.domain.tld

Edit /var/qmail/control/locals and remove host.domain.tld
