Optionally disable Watchdog message - Mailbox was checked and contained 0 messages

Currently I have a mailhandler feed that is importing emails via IMAP every minute. Every minute the following message is shown in Watchdog:

Mailbox MAILBOXNAME was checked and contained 0 messages.

It would be great if there was a way to disable this message when there are no messages to import (0 messages).

If there is a current way to do this, then I may have overlooked it. If not, then thanks in advanced for the feature request consideration.
