Today I received the following message from Spamhaus. The server they are talking about does only do a "low" volume of emails, so I've got no clue why they are emailing me about this. Anyone else here who got this email?
I've just received one of these too, slightly different and asking me to pay. (I'm a low volume user):
Same here Same happening to me but I'm not sure how do I use it in my website... does any Wordpress plugin use Spamhaus in any way? Mine comes from Gary Lessers and I have up to 4 emails from them, sent to [email protected], support@, postmaster@ and my gmail.
