Does this block things like the unconventional Google-filing trick of:

  myemail+90sdev@gmail.com
which gives me the “90sdev” tag for my emails, which still go squarely into my “myemail@gmail.com” address? I don’t know what the best route is, but I’ve certainly run into bad validators that block things that otherwise work, and that’s annoying. It seems to me the best thing might be to have a user twice input their address, then have the next step/confirmation done via email.

> unconventional Google-filing trick

Documented as "subadressing" in RFC 5233, and the default for both sendmail and postfix, amongst others. As such, often 'accidentially' supported by many mail providers even when undocumented. Google didn't introduce them, nor are they 'unconventional'.

TIL
I don't do blocking or differentiating. Emails are literal, for better or worse.
> bad validators

Possibly these validators are working exactly as intended and don't want you to know which service sold your email to spammers.

Then again maybe spammers are smart enough to strip of the + from email lists they purchase.

The latter was motivation to get my own domain so I can have unlimited unique addresses with a wildcard entry.
I never get spam that makes it through the default filter, so I am unsure if this works, but I do get zero spam in general since switching off gmail. I like giving silly businesses that ask for my email their business name @ my domain.

Most of the time they're too disinterested to notice. Oil change places always notice for some reason.

I'll look through my spam foldsr tomorrow and see who's been naughty.
