TLDR: Please give us a better option for handling email that is almost certainly dangerous, ie in my case email sent to an address that only receives dangerous email. Some suggested ideas at bottom.

I have a [service]@[myname].com email address, which I used many years ago to sign up for a service that is now defunct. It's one of many, many catch-all email addresses that I use on that custom domain.

Many years ago that email address was part of a hack/leak. I now regularly receive phishing email, or emails with surely-dangerous PDFs, to that address. No legitimate email will ever be sent to that address.

Unfortunately right now I only know of these options for handling these emails:
- Do nothing and the email lands in whatever folder alongside incoming non-dangerous emails
- Filter by TO address and send to trash or spam, where it sits among non-dangerous spam or emails I've deleted
- Filter by TO address and send to a custom folder "Phishing", where it is sequestered but still appears within my All Mail view

Here are a few ideas for how this might be done:

1) In Settings > Organizational Filters > Spam, block, and allow lists - enable blocking or Spam-marking emails by TO address, in addition to FROM address
2) In Settings > Filters - allow for filters that delete email without sending to Trash, which could be set to automatically delete any email for a given TO address
3) In Settings > Folders and Labels - allow for creating sub-folders of Trash and Spam, eg "Trash > Known Dangerous", which could serve to isolate known-dangerous emails from non-dangerous emails
