Hello, I'm running ISPConfig 3.1.6 under CentOS 7.3 with dovecot / postfix as per the multi-server setup. I can see mailbox quota information but not any mailbox statistics information ? I have read that dovecot should work with statistics but can't seem to figure out what is not being generated for this information to become available through the ISPConfig interface. Logs seem to indicate sizes but not sure exactly what ISPConfig is looking for.
