Error creating forwarder: Unable to write to the alias file.

Hi Guys,
One of our users is getting the following error when trying to add an email alias/forwarder.

Error creating forwarder

Details

Unable to write to the alias file. Let your administrator know that /etc/virtual/example.com/aliases is unwritable.

The file originally had the following permissions, which are normally fine:

-rw-------  1 mail  mail   25 Jul 19  2007 aliases

Routinely, I tried it with full 777 permissions, however it made no difference.

I also noticed the following empty file in the same directory, is it relevant?

-rw-rw-rw-  1 mail  mail     0 Jun 16 10:56 aliases.temp

What's going on?

Delete aliases.temp

Turned out to be an odd quota discrepancy.
