We just recently purchased Mail Assure with Cove Data Protection from N-able to achieve a similar goal, but unfortunately I don’t have any experience with it yet to advise if it is any good. It is an option though.

Are you using Route 53 for DNS? If so, would you mind sharing your monthly cost for that? Thanks again.

Thanks for the suggestion. Honestly one thing I don’t like about AWS and a lot of the major cloud vendors these days is the pricing structure isn’t very easy for me to wrap my head around and I’m never confident what I will be charged. I do have some services on AWS and so far I haven’t had any surprises but I do always have that concern. I will give Route 53 another look though.

Thanks for the detailed response! I will definitely check out unbound. Sounds perfect. And 2 cores and 2 GB RAM is exactly what I was hoping would be enough, so I can keep costs down.

All great questions! It will be a Debian Linux hosted VPS. Thanks for the input!
