Allow blocking senders.

[RokeJulianLockhart]

I don't want to disable an alias every time spam reaches one, especially because most spam I receive is from the same few addresses (yet can't be unsubscribed from; it's mostly phishing). Consequently, please allow me to block senders alias, recipient, and account-wide (the 3rd being the most important for me immediately).

You should just be able to block the sender from the email, no? When you receive the forwarded mail, it will be youralias+sender=[email protected]. So if you block that, you would just be blocking that specific sender, not the alias itself. It would still be great to have a place to do it in the Addy dashboard, but you shouldn't have to deactivate the whole alias. If I am missing something, then please let me know!

@Cascabel-dev, the example you provide would only block the sender from a specific alias. I need it at least account-wide to lessen currently common spearfishing attempts.

Additionally, most e-mail providers I've used (GMail, Outlook, and potentially Proton) appear to check whether a domain is in a whitelist and if not, block the entire domain, when it automatically detects spam from an address.

The solution I have in mind for this would only be able to block sends based on the SMTP FROM address (return path) and not the From: header. So it might not be as effective for services using variable envelope return path (VERP).
