Basic config on qmail

Under qmail source dir, run ./config to start a basic config. The followings will be displayed:

Your hostname is 
www.ericyu.com.
Your host's fully qualified name in DNS is server.linuxserver27.com.
Putting server.linuxserver27.com into control/me...
Putting 
linuxserver27.com into control/defaultdomain...
Putting linuxserver27.com into control/plusdomain...
 
Checking local IP addresses:
0.0.0.0: PTR lookup failed. I assume this address has no DNS name.
127.0.0.1: PTR lookup failed. I assume this address has no DNS name.
64.106.250.143: PTR lookup failed. I assume this address has no DNS name.
67.15.179.25: Adding 
server.linuxserver27.com to control/locals...
 
If there are any other domain names that point to you,
you will have to add them to /var/qmail/control/locals.
You don't have to worry about aliases, 
i.e., domains with CNAME records.

Copying /var/qmail/control/locals to /var/qmail/control/rcpthosts...
Now qmail will refuse to accept SMTP messages except to those hosts.
Make sure to change rcpthosts if you add hosts to locals or virtualdomains!
If there are problems with FQDN, run config-fast your.host.name and edit the files under /var/qmail/control directly.

Install qmail aliases

root:/usr/local/src/qmail-1.03# cd ~alias

root:/var/qmail/alias# echo adam > .qmail-root

root:/var/qmail/alias# echo bob > .qmail-postmaster

root:/var/qmail/alias# echo bob > .qmail-mailer-daemon

Setup daemontools & create control directories

If these tools are not installed, obtain the necessary packages listed below:
daemontools-0.70-8
ucspi-tcp-0.88-7

Then

mkdir -p /var/qmail/supervise/qmail-send/log

mkdir -p /var/qmail/supervise/qmail-smtpd/log

chmod +t /var/qmail/supervise/qmail-send

chmod +t /var/qmail/supervise/qmail-smtpd

mkdir -p /var/log/qmail/qmail-send

mkdir -p /var/log/qmail/qmail-smtpd

chown -R qmaill /var/log/qmail

create file /var/qmail/supervise/qmail-send/run

run

#!/bin/sh

exec /var/qmail/rc

create file /var/qmail/supervise/qmail-send/log/run

run

#!/bin/sh

exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t s2500000 /var/log/qmail/qmail-send

create file /var/qmail/supervise/qmail-smtpd/run

run

#!/bin/sh

QMAILDUID=`id -u qmaild`

NOFILESGID=`id -g qmaild`

exec /usr/local/bin/softlimit -m 3000000 \

 /usr/local/bin/tcpserver -H -R -v -p -x /etc/tcp.smtp.cdb \

 -u $QMAILDUID -g $NOFILESGID 0 smtp /var/qmail/bin/qmail-smtpd 2>&1

create file /var/qmail/supervise/qmail-smtpd/log/run

run

#!/bin/sh

exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t s2500000 /var/log/qmail/qmail-smtpd

Access Control

create file /etc/tcp.smtp

192.168.13.:allow,RELAYCLIENT=""
1.2.3.:allow,RELAYCLIENT=""
:allow

run

tcprules /etc/tcp.smtp.cdb /etc/tcp.smtp.tmp < /etc/tcp.smtp

Create the qmail rc file in /var/qmail/rc

#!/bin/sh

exec env - PATH="/var/qmail/bin:$PATH" \

qmail-start '|dot-forward .forward

|preline procmail'

Or if dot-forward is missing

#!/bin/sh

exec env - PATH="/var/qmail/bin:$PATH" \

qmail-start '|preline procmail'

Starting / stopping qmail

Daemontools will start qmail in a few seonds

ln -s /var/qmail/supervise/* /service/

Restart qmail

svc -t /service/qmail-send

svc -t /service/qmail-smtpd

Stopping qmail

svc -h

svc ?

Configure pop3 daemon

On Fedora, install uw-imap-2006e-2.fc5 using yum. Then go to /etc/xinetd.d and enable ipop3 service.

Integrating Qmail with Spamassassin

Spamassassin can be invoked at delivery time or at queue time. Obtain & install spamassassin rpm.

At delivery time:
Change /var/qmail/rc to

#!/bin/sh

exec env - PATH="/var/qmail/bin:$PATH" \

qmail-start '|spamassassin -P |preline procmail'

At queue time:
Rename /var/qmail/bin/qmail-queue to /var/qmail/bin/qmail-queue.orig

Create /var/qmail/bin/qmail-queue

qmail-queue

#!/bin/sh 

spamassassin -P | qmail-queue.orig

Create an account to store spamassasin setting

mkdir ~qmaild/.spamassassin 
chown qmaild.nofiles ~qmaild/.spamassassin 
chmod u=rwx,g=rx,o= ~qmaild/.spamassassin

Edit run script for qmail-smtpd

run

#!/bin/sh 

QMAILDUID=`id -u qmaild` 

NOFILESGID=`id -g qmaild` 

MAXSMTPD=`cat /var/qmail/control/concurrencyincoming` 

exec softlimit -m 4000000 \ 

  tcpserver -v -R -l 0 -x /etc/qmail/tcp.smtp.cdb -c `"$MAXSMTPD`" \ 

    -u `"$QMAILDUID`" -g `"$NOFILESGID`" 0 smtp qmail-smtpd 2>&1

The line with "exec softlimit -m 2000000" tells tcpserver, to limit all subprocesses to a maximum memory consumption of two (2) million bytes. If this results in to little memory the spamassassin process may die. Yury Gusev is using (by now) "exec softlimit -m 66000000". Please tell us your experiences. It should also be considered to run the spamassassin daemon, and only invoke spamc, the spamassassin client with this setup, instead of launching a whole spamassassin process for each mail.
