I have Zimbra 5.0.10 currently (upgraded this weekend from 5.0.6) FOSS.
Installed on Ubuntu JeOS 22.214.171.124 all up to date. I had this same problem on my old server that I upgraded from, I ended up deleting the files then it never recreated the log files.
My /var/log directory gets to be over 2GB in the matter of days, which then fills the hard drive. I have been trying all day to reduce or eliminate the logging of all the postfix traffic. I do not need this information. I have tried to turn off postfix logging, but every time I restart postfix the settings go back. So somewhere its being re-rewritten.
I have made these changes (as zimbra user):
zmprov mcf zimbraLogRawLifetime 1d
zmprov mcf zimbraLogSummaryLifetime 7d
zmlocalconfig -e ldap_log_level=0
zmlocalconfig -e zmmtaconfig_log_level=1
Then in /opt/zimbra/postfix/conf/main.cf:
smtpd_tls_loglevel = 0 (Always goes back to 1 which I assume is default)
Also in log4j.properties.in I changed most the 'DEBUG' or 'INFO' to 'WARN.'
Please help me reduce my log files or turn them off for email traffic. But obviously if I need them I will re-enable them.
Thank you in advance!
