Re: [Devil-Linux-discuss] Postfix

to get information from postfix about your settings, try:

postfix check 2>&1| grep -v "not owned"

and look at recent log messages (e.g. after trying to send an email):

cat /dev/vcs10 | grep postfix

or my DL page http://www.edendevelopments.co.uk/dlsetup#postfix might help
