This server is not an MTA

[Tripple]

When I log in to the admin page of my Zimbra server I have the same error with the tab 'Message Count', 'Message Volume' and 'Anti-Spam/Ati-Virus Activity":

This is not an MTA and will not have any MTA statistics.

Never seen this message before?

Some extra information:
Release 6.0.7_GA_2473.RHEL5_20100616214455 CentOS5 FOSS edition.

There is a bug report filed on this problem (I don't have the number handy) search for it and add your comments to it.

Message is gone too, after removing the old .rrd files, but I stil dont' get graphs from any stats, 'data not available'.
