Sendmail Error

["Christos E. Chrisostomidis" <christos polichromo gr>]

Dear All,

I am running sendmail (8.12.8-5) on a RH9.0 box
and I have recently found the following error in the maillog:

Forwarding errors:
    /dev/null/.forward: World writable directory: 18 Times(s)


The permissions in /dev/null are rw-rw-rw-

Have anyone any idea what this could be ?????

Best Regards
Christos
