The Qmail package from Dotdeb has been built with SMTP-auth features (but disabled by default). Here is the way to use them…
Installation
First of all, we suppose that :
- you installed the last Qmail and Vpopmail packages from Dotdeb
- you’re launching them using the bundled init scripts (with tcpserver)
Configuration
To enable SMTP-auth, you just have to edit the /etc/init.d/qmail init script and replace these lines :
sh -c "start-stop-daemon --start --quiet --user qmaild --pidfile /var/run/tcpserver_smtpd.pid --make-pidfile --exec /usr/bin/tcpserver -- -R -u `id -u qmaild` -g `id -g nobody` -x /etc/tcp.smtp.cdb 0 smtp $rblsmtpd /usr/sbin/qmail-smtpd 2>&1 | $logger &" |
by these ones :
sh -c "start-stop-daemon --start --quiet --user qmaild --pidfile /var/run/tcpserver_smtpd.pid --make-pidfile --exec /usr/bin/tcpserver -- -R -u `id -u qmaild` -g `id -g nobody` -x /etc/tcp.smtp.cdb 0 smtp $rblsmtpd /usr/sbin/qmail-smtpd /usr/sbin/vchkpw /bin/true 2>&1 | $logger &" |
Then, we have to setuid /usr/sbin/vchkpw :
chmod u+s /usr/sbin/vchkpw |
and restart Qmail :
/etc/init.d/qmail stop /etc/init.d/qmail start |
The result
You will now be able to use the SMTP PLAINTEXT authentification. You just have to configure your favorite mail transport agent…
