Hey guys.

I know there have been several post about this issue and I have tried a lot of the solutions, but none of them have solved my issue.

First a bit of info of the installation:
Release 6.0.10_GA_2692.RHEL5_20101215171125 CentOS5 FOSS edition.
It has an internal ip-address, and a DNS that has splitt up internal and external resolves. I dont think that is the problem though, but it might be worth mentioning.

So, from the Zimbra wiki, about Logger:

I have tried to restart anything I have found, but have'nt found anything that solves this. Any more hints?
