I am looking for some affordable email hosting for my many, many sites. I don’t get a lot of emails on each one but I have a lot of domains.
Your service looks pretty great, however I have a concern over privacy.
These sites are in competitive markets where competitors will try every trick in the book to uncover my other websites, even if they only know I own one site.
I am using Cloudflare for my CDN which masks the majority of the traffic (as the cloudflare CDN services host 1000’s of sites, so while you could potentially see my sites are connected to the same IPs, it’s not so much of an issue as it is mixed in with thousands of other unrelated sites).
I also protect my domain privacy, so no issues with WHOIS.
However, some malicious individuals were able to identify the other websites I host (with Cloudflare as CDN) by analysing the mail server I use. Cloudflare does not support mail ports so the mail DNS records expose the IP of my server (which hosts all my sites, on cPanel). This can then be used to see all my sites.
If I use your service for mail and change the DNS records, will people be able to see my other sites and connect them, or is it like Cloudflare where thousands of accounts are hosted on the same IP/Servers, somewhat masking the relationship between sites?
Thank you for your help, and I appreciate this is an affordable service, so no rush on the replies but I appreciate someone with the correct knowledge getting back to me as soon as is possible.
