The most important button on a machine in a work place is EMERGENCY STOP not the start button On some machines they even have several buttons that can be reached from different positions or areas.. Its also a bit like a car,, more experienced driver want to know "how quick does it stop" whilst the young and reckless wanna know "how fast does it go??}

Having the worlds most secure mailer is no good if U cant keep out people that are attacking your machine via trojans in jpegs .. that come straight thru the front door

Maybe there is a block sender but if there is its too well hidden

Yes, I may have to look for another email provider due to the lack of blocking spam.

Display an "Automatically Block" button by which users could designate senders they would like to block to prevent clogging up their Inbox.

If you filter out all email as spam that is not from .com, .net, .gov, .us, .ch, .org (and a few others) you'll lose 75% to 85% of the spam and you'll maybe lose a few good emails, but you'll have to dig them out. Then you can adjust the filter to allow for these.

With a Sieve you can issue a reject if you put reject in the modules list. It's undocumented (well ProtonMail says it's not possible). You can also make it look as if it was genuinely rejected via SNMP if you know the address and half way put something together in the reply text.

Like I told the Thunderbird zombies, I can break anything.

mailwasher had a feature that would send a "bounce" message to unwanted senders. "bounce" is a msg back to the sender that the target email address does not exist. i.e. if/when you delete your account from an old email (leave a company, chnage providers). Spammers listen for these bounces and remove targets from thier database.

Would also like to be able to block the sender's whole domain like you can in Outlook.

Absolutly needed!

Agreed, it would be great if known e mail addresses could be blocked whilst having an auto-reply set saying the 'address does not exist' or similar.
If it were a paid service I would gladly pay,
Thanks

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.

Seriously, there aren't more people that are upset of this lacking feature?

I also find the lack of ability to block spam mail annoying....

In gmail I created a filter which sends an autoreply bounce to unwanted domains, what it does is trash it and then send the autoreply, which the autoreply I copied and pasted a real BOUNCE email and that way it tricks some servers and most users to think it really bounced! It works.

Or at the very least, to BLACKHOLE the email so you never see it, but ideally, BLACKHOLE while sending a bounce request.

I don't see a reason to not using filters instead. Just because seeing an potentially unwanted E-Mail causes you emotional harm, doesn't mean that the platfrom should be reworked. Just don't peek into your SPAM folder :)

great I idea.

Agreed with that comment:

"WE HAVE THIS!
You can CURRENTLY just add a filter to send email to trash for address!

Dont waste the devs time when there are real issues to solve!

I second the idea of being able to block a whole country.

This would be a great way to handle Spam

ProtonMail is great and I am a big fan. But why is this not standard integrated to your account?

ProtonMail, please tell us ............
