Help: postsuper: fatal: scan_dir_push: open directory defer: Permission denied

Nickalf · 01-16-2012, 02:45 PM

Hi all,
I searched for answers but they are old and not really solved.

I installed a new server and created a main.cf but cannot get Postfix to run - get the error:

postsuper: fatal: scan_dir_push: open directory defer: Permission denied

Can you help/guide on how I can fix this problem ?

Thanks,
Nick...

From what I'm finding, it appears to be an issue with the mail queue not being able to be read by postfix. You will want to review the main.cf file to find the queue directory. By default it appears to be /var/spool/postfix.

Run:

Code:

ls -la /var/spool/

If you find that the postfix directory is owned by root or anything that's not postfix run:

Code:

chown -R postfix /var/spool/postfix

If you find the queue directory is a different folder, simply modify what you see above.

This post comes up high in google's results for the topic so I hope someone can respond and add to it. I have the same symptom.

Changing the ownership of /var/spool/postfix to postfix:postfix does indeed allow postfix to start without this error.

But -- then on startup, postfix warns that /var/spool/postfix is not owned by root!

What's really right?

It's been awhile since I worked with this issue, and I no longer have the test server that I had before. However, this may not be an ownership, but actually a permissions issue. Try chown'ing the /var/spool/postfix directory to root, but change the permissions to 644, or something where another user like the postfix user can read the contents.

Oh, Postfix have a good solution for solve it:

Code:

/opt/postfix/usr/sbin/postfix -c /opt/postfix/etc/postfix/ set-permissions

Of course i forced to use "-c" because i compiled into /opt/postfix, i didn't use default directory.
After run once, do starting postfix:

Code:

/opt/postfix/usr/sbin/postfix -c /opt/postfix/etc/postfix/ start

Just like to say a big thanks to this old thread, helped me get my postfix started on a centOS 6.5 dist.

Code:

chown -R postfix /var/spool/postfix

followed by

Code:

chmod -r 644 /var/spool/postfix

did the trick after I was getting an postsuper: fatal: scan_dir_push: open directory defer: Permission denied error

big thank you !!

1. As root, run the zmfixperms command to repair any potential permissions problems with files under /opt/zimbra:

/opt/zimbra/libexec/zmfixperms

2. If you need to check /opt/zimbra/store and /opt/zimbra/index as well, you will need to use the -extended option. This will take much longer to run - potentially several hours in large environments - so run it only if necessary. Run this command as root:

/opt/zimbra/libexec/zmfixperms -extended
