Postfix chroot + SASL authentication (saslauthd)

November 18, 2006 - 1 comment

Scenario :

You run Postfix non-chrooted with SMTP auth though SASL authentication (using saslauthd)

The issue :

When chrooted, Postfix needs access to saslauthd sock file, which is not in the chroot area

The fix :

We consider Postfix chroot is under /var/spool/postfix

mkdir -p /var/spool/postfix/var/run
mv /var/run/saslauthd /var/spool/postfix/var/run/
ln -s /var/spool/postfix/var/run/saslauthd /var/run

Configure Postfix to run chrooted (script available here : http://www.wains.be/pub/postfix-chroot
