Unusual Filters

There are typical email filters. For example, if I get email from a particular email address that isn’t spam but I never ever want to see it in my inbox, I set up a filter for it to archive it or throw it in the trash, problem solved.

There are also smell-test filters. For example, I don’t have to read an entire email to know it’s just some unwanted hot garbage solicitation email. I don’t know what I’ve done recently but my god if I don’t get a lot of these recently. It’s not a programmatic filter, it’s just me instantly knowing an email is useless and whisking it away.

Back in programatic filter town, how’s this for a weird one?


Email me at [email protected]

PERSON – I’ll read the plain text portion of your email

– I’ll trim whitespace from the start and end

– I’ll hash it using SHA-256

– If the hash starts with seven CARDINAL ( 7 CARDINAL ) zeroes, I’ll forward it along to my real email — jordan GPE ( @jdan ORG ) October 14, DATE 2023

If you don’t send 0000000 CARDINAL as the starting plain text of an email to Jordan PERSON ’s email here, it’s just lost to the internet tubes.

Pretty niche, but I could see using this for something like an extreme hiring prerequisite. If you’re applying for a job as a developer, maybe even an email-focused developer, some kind of “test” like this to apply would be clever.
