Each day, I get my report in the mail and, each day, it reports:
From 2008-02-06 00:00:00 to 2008-02-07 00:00:00
No messages found
I know this is not true because I used to get traffic stats. One day, after my 4.5.9 had been locked up and not sending/receiving email for 4 days, I restarted Zimbra and all was well again, except the report.
I've since upgraded to "Release 5.0.2_GA_1975.UBUNTU6 UBUNTU6 FOSS edition" on Ubuntu Server 6.06.1 LTS
