Who hosts what mail? MBP Spotlight is the series here at Spam Resource ranking the top mailbox providers (including B2B) based on their counts of MX records in the top ten million domains. Some entries might have more info, some entries might have less, depending on what information I know about them and what information I can find online.
To count rankings, I took a snapshot of MX records for the top ten million domains, and then rolled them up based on the domain name hosting mail for each domain. That shows me how many domains have their inbound email hosted by hosted by “*.google.com,” “*.outlook.com,” etc.
If you’re finding mail rejected when trying to send to Strato customers at domains with an MX record pointing at rzone.de, they do not appear to publish Postmaster or deliverability help page. However, they do have an online help section, with contact info, that does include email-related guidance.
