any update on this i want this I have this issue

With my catch-all email address, I use a different email for each account I setup online. Sometimes, that email is leaked or sold and my Spam starts filling up. I'd like a way to be able to burn specific email addresses so any email going to that is bounced back to the sender as undelivered. I know I can filter them to the trash as read, but I'd like to completely remove the possibility that the spammer knows it's a valid email address.

I vote for a Bounce feature as well.... Email has become so cumbersome I am tempted to quit it all and do phone texting only.

To have a option selected when sending a email, and get bounce-back messages for successfully delivered messages. Giving us the physical/documented proof that the email was sent and, at least, arrived to the server recipient. This was one of the main reasons that I upgraded to PRO, thinking that had this feature embedded :)

Please add it to the current filter options :)

When Fastmail first came out they had the option to click "Bounce" on any email. It would be returned to the sender as if the address did not exist. Very handy for spammers. No list was kept, and if the spammer persisted, you just had to continue bouncing their messages.

I would like a feature to generate a non-delivery report on an email I receive e.g. to say that the user (me) doesn't exist.

I get a lot of junk messages which I believe some mass mailers tidy up their lists based on bounce backs and target active mailboxes.

Should be able to select individual emails and just click "bounce"

Having a way to bounce an email back to sender so they get the message that they've been blocked!! Having things go to our spam folder is just another folder of something I have to deal with. On occasion I do get emails I truly would like to block or bounce back to sender so they see their msg was undeliverable to me. Better yet, let us "Title" the bounce back to whatever we want to say, like "Msg undeliverable. Receiver does not take msg's from Alien maggots" Oh & include w/the free service. Most free email servers have a bounce back feature or theirs an app you can download. Can't do that w/you since the point is anonymity. PLEASE pretty please!! Looks like you've had tons of people begging for this in each category........

Back when I was a Mac user, Apple Mail had a really handy bounce button, which would bounce unwanted emails and make your address look invalid, thus unattractive to spammers, bots, etc. I would think that a bounce function/button would be (hopefully) pretty easy to implement and very useful in deterring spam.

This blog suggests bouncing messages from gmail.com users with a DSN error "The person you are trying to contact hasn't accepted Gmail's privacy policy. Please try sending the email from a regular email provider."

Allowing Protonmail users to enable a bounce like that for incoming messages would be an interesting way to let them assert their right not to be under Google surveillance.

Dunbar number. look it up, I believe it's somewhere between 125 and 250. I believe this may also be a concept that Google started with way back in 2004 while in beta testing. But you look at most social networks and it seems the people who need their dopamine drip prefer to rack up as many "acquaintances' as possible. Makes sense to revisit contacts every now and then as changing circumstances may require different contacts.

I would like to be able to suppress or spoof your bounce message. It is a metadata leak.
