I have a custom milter in C ( for email archiving ) which works fine on
my servers with postfix 2.8+. ( RHEL 5.5 )
When I tried to install the milter on a ubuntu box with postfix 2.7 ,
unless I create the socket inside spool directory for eg.
/var/spool/postfix/$path/milter.sock
Postfix does not seem to find the milter.
Why so ? I cant see any chroot jail configured on the server. Is chroot
on by default ?
This is the postconf -n output
