I would be tempted to implement a custom SMTP server that accepts every email as if that target mailbox exists and collect them on a nosql db (just for curiosity and technical challenge) though I have no idea if I'd face any legal issues.

It's called Catch-All; I have it set up for my Google For Work account (e.g. I have a gmail that receives @my domain). So, you could use gmail to catch all e-mails to @gail.com; no need for a 'custom SMTP server'.

You can also do this with a real MTA; no need for Google, either.

I wanted this and I couldn't find it, thanks!

How much spam do you get from the Catch-All?

[erdemozg]

Thanks for the info. I didn't know it was that easy.

I made a service that does this ( https://disposeamail.com/ ), and I am constantly asking myself if it's worth it. The PostgreSQL database takes up over half the disk space on the VPS I run it on, and that's only after a few months. And of course it's almost all ultra low quality spam.

You're doing the Lord's work, son.

This is a great service/idea. Have you considered a donate button to help support it?

Why would you? It's standard practice to set up a catch-all for your domain and you can just configure postfix to do that.

Ignorance of the law isn't an excuse.

Or just pretend that you are a gmail mail server and store the credentials that are transmitted when people add the account to their mail app.

Would DMARC not prevent this?
