Bans not listed emails

It started blocking emails, that are not listed in our ban list, not even as fragments.

I hate to ask it this way but … Are you sure? If you have those partials in your block-list for WP comments, it’ll grab those.

Hey, yes – I tested several times.
I’m now testing if it will make a change id I add list with “@” and without.

You would like me to send you a full blocked list?

I used this list:
https://knowledge.hubspot.com/forms/what-domains-are-blocked-when-using-the-forms-email-domains-to-block-feature

What emails (or kinds of emails) is it blocking? That’s a pretty massive list and includes yahoo.com which is totally gonna net you false positives.
