Arsenjev on "[Plugin: Wordfence Security] Emails no longer received related to former domains"

Hi,

Right now I use Wordfence on 3 domains (I like it very much, thank you!) but after adding it to each new domain, I do no longer receive email notifications/alerts related to the former domains.
Did I do anything wrong and how to correct this?

I'm using Wordpress versions 3.4.1. and 3.8.1.

Thanks.
