I have ZCS 8.0.2_GA_5569.FOSS installed in CentOS 6.04. In recent times i find few mails are missing. When a user sent mail to two internal mail id's the mail did not reach the intended recipients, but the same mail when sent again after an hour reached both the mail id's.
When i looked the mail log "/var/log/zimbra.log" i found log for both the mails (the one which was not received and the mail which was not received).
Can anyone guide me on how to proceed further on this.
