Package: postfix
Severity: important
Tags: patch
I have a suggestion to a patch for the rc-init.d script for postfix in
Sarge. Patch at the end of this email.
The patch solves the problem when you have enabled virtual delivery in
postfix thru an external source like a database or ldap and postfix runs
in chroot mode, which is the default configuration in Sarge. The problem
is that you in this situation will have to create a hardlink from the
external sources socket into the jail but at this moment this is not
done automatically which means you have to do this by hand after the
server has started. On several occasions I have restarted the server but
forgotten this which led to a stalled mail delivery system until I did
it. To prevent this situation in happening again I have made this patch
for the init script. At present it only handles mysql, which I use, but
could be easily extended to postgresql and openldap.
One requirement though is that the start order of postfix and the
external source is important so to make sure postfix starts after the
external sources it's start order should be 21 instead of 20.
