Is there anyway to reject an email that is addressed to more than 5 recipients and have it bounce back to the sender with gmail? This is a long shot. Essentially I just don’t like receiving these “hey everybody! look at this” type of emails and I want people to know I don’t read them or even want them to come to my inbox without having to actually get all shirty about it.
Having looked at the advanced search options, as far as I can tell, there isn’t even a way to filter by the number of recipients and even if there was the only thing you can do is to delete or archive the message, you can’t make it bounce.
