Gmail marks emails from BridgeDB as spam

I noticed that Gmail now tosses emails from BridgeDB's autoresponder into its spam folder:

BridgeDB's instructions should mention that users should take a look into their spam folder if they didn't get a response. Ideally, we should find a way to prevent this from happening. I clicked the "Report not spam" button of every single BridgeDB email. I hope it will tell Gmail's classifier that this is a false positive.
