Barracuda Central is serious. They're operated by Barracuda which focuses on security for businesses and such. They have security gateway solutions that incooperate their blacklists to block traffic to bad IPs and websites. Admittedly their prices for such solutions are quite high though but they have their uses and many business users.

I so far had no issues on getting IPs delisted if the malicious activity has stopped. The sites or IPs had been removed within 48 hours usually.

Thanks for this info @"Hidden Refuge".  You're right, the domain is no longer listed and that made my DNS Inspect rating jump from B rating to A.  When I submitted my IP to Barracuda for delisting I also got rid of all of the mail records that VestaCP created for me. It shows I don't have MX records. I've never used mail with this domain before so am quite curious how it ever could have got blacklisted. Anyway, am happy as looks as though the domain and IP are doing OK for now.

Maybe the previous owner of the IP address might have used it as a mail server? It depends. Maybe the VPS 15's previous hosting owner had the IP block and his customer had abused it? There are numbers of possibilities that the IP has been blacklisted due to spam mailing by previous IP owners.

When I checked again it looks as though the domain was black listed (not the IP), i.e. mail.domain.net. Which has me very curious, as I've never ever in the life of the domain run a mail server before.

I then checked, and looks as though there's another domain that is similar to mine that may have been the problem.

I.e. my domain is dhwebs.net and there is also a domain called dhwebs.com. Maybe someone wanted to report mail.dhwebs.com, and by accident went for mail.dhwebs.net.
