Notify admin of new registrations from specific domains

[CycleChat]

Hi,

We have a couple of people who've been banned but keep returning.

They use specific domains, but I don't want to outright ban those domains from registration in case I exclude genuine new members.

I wondered if anyone knows of a mod/hack that will allow me to list domains and have VB email me each time a new registration comes in for any of those domains.

This way I can be pinged for the domains I'm concerned with.

Cheers,
Shaun

PS. I know I can check all the new user emails, but this would just help make specific ones really stick out!!
