Zimbra 8.0: Warning create file maildrop/XXXXX.XXXXX permissions denied

Question

I have Zimbra 8.0 running over Ubuntu work fine but I have a warning:

postfix/postdrop[XXXX]: warning: mail_queue_enter: create file maildrop/XXXXX.XXXXX permissions denied

The problem is that 800MB were generated for this warning in only 4 days.

I've tried:

• executing zmfixperms as superuser
• executing zmfixperms -e as superuser
• executing zmfixperms --extended as superuser
• changing owner/group queue_directory to postfix/postdrop
• set full permissions (rwx) to queue_directory

And log is still growing

queue_directory: /opt/zimbra/data/postfix/spool

drwxr-xr-x root    root     /opt/zimbra/data/postfix/spool 
drwx------ postfix postdrop /opt/zimbra/data/postfix/spool/maildrop

Solution

I just ran into the same problem. Turns out that postdrop was still running as the zimbra user after having fixed permissions and restarting zimbra.

Bringing down zimbra and then killing the postdrop task fixed it:

$ sudo su -
$ service zimbra stop
$ killall postdrop
$ service zimbra start

If you haven't done so already, make sure you've stopped the Zimbra services first as the Zimbra user, then run zmfixperms as sudo.

yes i did it. always stop zimbra with su - zimbra -c "zmcontrol stop" before any change
