Statistic event generator sends no mail to user

We have configured some monitors in events4.nsf. For all statistic events/alarms with severity “fatal” i want to send a mail to one notes-user. But no mail is send when an event occurs. In the events4.nsf there is only this one event handler for statistics. When i select “log to database” instead of “mail” the event is logged to statrep.nsf.An other event handler with the option mail for events of type “monitor” sends the mail well.

Any new ideas on this? this seems to work in 6.5.3 code, but not in 6.5.1
