Open Source Document Management System | OpenKM

Hi, I have configured email notification in OpenKM but it has a strange behavior.
Sometime the notification work just fine and an email does arrieve but many times there is no email at all.

I have no clue why it work sometimes and doesn't work other times.
I can say that there is no problem with email server.

Next question:
What is "schedule.ui.notification" property?

Schedule.ui.notification is time cycle for dashboard, has no relation with it.

I suggest you log the Mail Utils class com.openkm.util.MailUtils
Take a look here about how do it in 6.2 http://wiki.openkm.com/index.php/Debug_log_info
