Parent directory does not allow write, or one of the directories didn't allow search (execution) permission

If you have vm-pop3d (mbox) and get the following error when creating a domain:

Parent directory does not allow write, or one of the directories didn't allow search (execution) permission

Try typing:

chmod 1777 /var/spool/virtual

For version 1.32.4, the error message will be more clear, including the path name.

If you ran into this error, then next time you try to create a domain, DA will say it already exists.  To solve that, go to:
Admin Level -> DNS Admin

and delete the domain in question, then you can try again.
