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.
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.
