The registry setting was not there so I created the entry.
MailStatsDeliveryTime with a value data of 18:00.
Gave a reboot of the server as well but it did not work.
The server is Windows 2012 R2 and we run this as a service.
So I either added it incorrectly or this is possibly different for the latest version?
Im running the latest version of teh Kiwi Syslog server with Hotfix 3 applied.
Any other thoughts on what I may have done wrong?
