I'm on the hunt for a good inbound spam filtering service for a small business. We're dealing with under 30 mailboxes split between two domains, and I really need to filter emails before they hit the users' devices. I'm struggling with the existing Control Panel settings and filters—like the one I set up for C0STC0—but users are still getting inundated with spam. I'd appreciate any recommendations for reliable services that can take care of this problem without requiring a ton of manual rules to be set. I also found some old suggestions from a previous discussion, but I want to see if there are any current options to consider!

Are you using an on-premise email server, or is it something like Office 365? Understanding this could help narrow down the best spam solution for your needs.
Stop trying to control spam through M365—it’s not meant for that level of email filtering. For a setup like yours, it's way easier to use a dedicated MX filter. I'd suggest going with options like Proofpoint Essentials, Barracuda, or SpamTitan. These are more set-and-forget solutions that will save you a ton of headaches instead of wrestling with rules.

I’ve got the mail hosted with Hostgator, but I don’t have WHM privileges—just access to the Control Panel.
