Router: notes.ini setting for MailLogToEventsOnly being used (note - this option may now be configured in a Server Configuration document)

We try to reduce the logging to a minimum and so we put inside of the notes.ini the entry MailLogToEventsOnly=1.Now we see every 5 minutes on the console the message:

Router: notes.ini setting for MailLogToEventsOnly being used (note - this option may now be configured in a Server Configuration document)

I don’t understand this hint because there is no possibility or field in configuration document where we can configure this behaviour.

Has anyone an idea?

The router is printing this message but I don’t know why and who can I suppress this message.
