I use my own domain and have a catch-all. I usually enter the domain name as the identifier. I.e. here it would be [email protected]

I sometimes do the same. It's weird to me that some places immediately sell your email and other orgs do not. Like a graph database conference seemed to lead to a lot of new spam.

It’s not some conference, it’s some asshole who has the ability to implement that kind of behaviour. I bet loads of people working at that graph conference didn’t agree but either didn’t know or didn’t have a say in the activity.

If you use Google Mail (and the email field in the form lets you) you can do <youremail>+<whatever tag you want>@gmail.com to track stuff like this.

It works for common spam, but it does not really work for curated lists because they can remove it.

(I think it is also an RFC standard, not just gmail, but don't quote me on this).

Not an RFC standard but it is a "de facto" standard. Everyone implements it, the config line for it is just commented out on postfix, super easy to use.

Spammers aren't dumb -- this gets stripped.

Next logical step would be having <youremail>+<secretKey>@gmail.com as the real email and <justyouremail>@gmail.com as spam box.

Clearly you like them because you use them a lot.

Anything about them you mislike?

That is a great idea. I really want my email hosted some place and that I could write my own "post arrival" simple business logic.

You can do this in gmail with filters, unless I'm missing something about the use case.

Maybe it's too early, but I don't get it. If the spammer doesn't strip "+<secretKey>" then you get spam in your real inbox. Btw, what is so secret about the secretKey if you post it on the internet?

You give different secretKey to each recipient. This way you know who leaked your email.

I’m pretty sure you can insert or strip periods ‘.’ in gmails too

Use temporary email alias? That's what I have been doing.
