There is a strange problem with our installation - we get the daily mail report only once - the day after zimbra is started/restarted. The following days, there is no daily mail report.
On running the following command as zimbra:
No errors or warnings are seen on the console but, there is an error entry in /var/log/zimbra.log:
zimbramon: 4039:err: 2007-08-14 11:51:55, zmdailyreport: Failed to email report: Died at /opt/zimbra/zimbramon/lib/Mail/Mailer.pm line 285.
Where should I start looking to fix this problem?
