Hi I am using zcs 8.0.7 open source

The built in administrator "admin" not getting notifications.
if I give the command /opt/zimbra/libexec/zmdailyreport I am able to see reports, but this is not getting mailed to admin

the command zmlocalconfig | grep smtp_notify gives
smtp_notify = yes

the command zmlocalconfig | grep admin@mydomain.com gives
av_notify_user = admin@mydomain.com
smtp_destination = admin@mydomain.com
smtp_source = admin@mydomain.com

but I am not getting any mails, few days before I got a DNS database message full message and I solved using this My IT notes: zimbra CRITICAL DATABASE ALERT LDAP primary MDB database is 90% full

will this be a cause? can any one help me on this

Regards
Vivek
