comment Mystery IP address attached to Windows Server
I don't think the conclusion that 90 is responding makes sense but it would make sense if the sequence 8F, 90, 91 belonged to that same machine. Is there a third interface? (For iDRAC?)

comment what does this mean Superfluous name server listed at parent: ns52.domaincontrol.com?
@simon Regarding how it disappeared I think you would have to reach out to the relevant service provider to see if they can provide any kind of audit log for changes to your zone data, alternatively if they had any problems with their service that caused the data to change by itself. This part of the question does not appear to be answerable by anyone else but the service provider as it's not a question about dns per se but about what has happened in their environment.

comment Windows DNS not picking up change to external website A record
The SOA REFRESH field tell servers hosting slave zones how often they should check if the zone has changed on the master (as kind of a baseline in addition to the notify messages normally sent by the master).

comment Alternative to postfix with SNI certificates + Dovecot compatibility
@TheQuantumPhysicist But for smtp w/ TLS the certificate would be for the mail server name, not all domain names that the mail server deals with.

comment Alternative to postfix with SNI certificates + Dovecot compatibility
Can you explain the scenario where a single certificate for a single name would not suffice in the context of smtps? I think that scenario is unclear at best and I would assume this is the reason why it's not supported.

comment RapidSSL: domain name does not match the certificate common name or SAN
I did not suggest checking with different tools but verifying that you are actually using the certificate you have purchased. You say that you have purchased a certificate for "app.domain.com" but also that the certificate you are using is for "ip-172-XX-XX-XXX"; that does not sound like it's the same certificate.

Are you sure it is the same certificate? It doesn't sound like it based on what is stated in the question.

@jasondancks The main problem I have with the edit is that there's no longer any clear question.
