We've set up a burglar alarm system that sends notification e-mails to a Gmail account. The issue with the burglar alarm is that it is too sensitive, and sends multiple e-mails for the same "disturbance." The message bodies aren't exactly the same. These near-duplicates are sent inside a window of less than 30 seconds.
I'd like to use Gmail filters to delete near-duplicate messages that are grouped within that 30 second window. A new message that is received outside of this window shouldn't be deleted because it's considered a separate disturbance. Is this possible? Much appreciated!
