We have CentOS 7 running, and previously had
postfix installed (it is currently uninstalled). After removing
postfix we checked the
/var/spool/postfix/maildrop, as the
df -h command was reporting over 9GB of usage in that directory.
There were hundreds of thousands of files in the directory (we removed them in order to free up space).
My question is, why were there so many files here? We had a lot of crons setup in the root
crontab file, but shouldn't
postfix have sent the cron result email files to the root users' mailbox?
