Greylisting Error switch into root account

[Wetty]

Hello,

I am using Plesk 9.3.0 on an Ubuntu 8.04 vserver.
When I enable Greylisting, I get the following error messages:

Feb 17 18:08:00 h1613293 greylisting filter[21668]: Starting greylisting filter.
..
Feb 17 18:08:00 h1613293 greylisting filter[21668]: Unable to switch into root a

Feb 17 18:08:00 h1613293 qmail-queue-handlers[21663]: LOG Internal error in hand
ler '05-grey-gO4U1k'. Skip handler.

What does this mean, how can I fix it?

Btw: I have this on 2 machines

Regards
Thomas

It is not OK. You have

0777/-rwxrwxrwx

But should be

4550/-r-sr-x---

 

[Wetty]

Okay,

changed. So far no errors.

Thanks
Thomas
