I've just installed iRedMail on a fresh Ubuntu 16.04.
Since the beginning, postmaster is constantly receiving these emails:
Object:
Cron <sogo@ip-172-31-21-98> /usr/sbin/sogo-tool expire-sessions 30 2>/dev/null; /usr/sbin/sogo-ealarms-notify
Message:

On the sogo log I just see some of these lines:
May 19 02:43:56 sogod [3013]: <0x0x5580870da5a0[WOHttpAdaptor]> notified the watchdog that we are ready
but they are old.

Everything seams to work fine though.
Thanks!
