Does anybody know if its possible in the IMAP Sensor to search for multiple keywords? I use the IMAP Sensor for checking if our backup was successful. The mails go into a specific mailbox and if any email has the subject ERROR the sensor turns red. Now there is a possibility that the email could have the keywords WARNING in the subject as well. Do I have to create an additional sensor, or is it possible to search for keyword WARNING "or" ERROR?
