POSTFIX – How to fix “warning: mail_queue_enter: create file maildrop/XXXXXXXX: Permission denied”

Following a server crash I started receiving errors as listed. Here is how I fixed it:

service postfix stop
 killall -9 postdrop
 postfix check
 service postfix start

If ‘postfix check’ returns errors – look through them and fix them one by one then run that command again to verify if everything is OK.

If you still having problems try:

chgrp -R postdrop /var/spool/postfix/public
chgrp -R postdrop /var/spool/postfix/maildrop/
/etc/postfix/post-install upgrade-permissions
/usr/sbin/postfix set-permissions

Re-registering the WMI components (Ref WMI FAQ)

The .DLL and .EXE files used by WMI are located in %windir%system32wbem. You might need to re-register all the .DLL and .EXE files in this directory. If you are running a 64-bit system you might also need to check for .DLLs and .EXE files in %windir%sysWOW64wbem.
To re-register the WMI components, run the following commands at the command prompt:

  • cd /d %windir%system32wbem
  • for %i in (*.dll) do RegSvr32 -s %i
  • for %i in (*.exe) do %i /RegServer
