Usually daily when the log rotates I get a compressed mail log file in the format maillog.day.gz under the /var/log and stays that way for a month then gets overwritten by the current month maillogs. Now all the compressed logs under /var/log are for April and nothing for June except of course the maillog file that shows daily stats. My logrotate works fine as I can see that from the maillog. It just suddenly happened and I have no idea how to solve it.
I used to have Webalizer installed but then this happened I think after un-installing.
