Mail history, by date
Each MX change is recorded the day it appeared. See which provider a domain used, and when it moved off, without asking the previous admin.
Past MX records
See the MX records a domain used to use.
Mail breaks quietly. An MX record changes, delivery shifts to a new provider, and nothing tells you when. DNSTimeMachine keeps a domain's past MX records so you can see exactly when mail routing moved.
For anyone searching past MX records, historical mail server, old MX records lookup, or when did MX records change.
How the history reads.
One domain, every record, each value stamped with the day it first appeared. That is the whole product: the past DNS you cannot get from a live lookup.
SPF and DKIM alongside MX
Mail problems are rarely just MX. DNSTimeMachine keeps the TXT history too, so SPF and DKIM changes line up with the routing changes.
Built for the post-incident question
When delivery breaks, the useful answer is what the mail records were before the change. That is exactly what the history shows.
When teams reach for this.
- Mail stopped arriving after a provider migration
- SPF or DKIM broke and you need the old value
- Confirming when a domain left a mail host
- Investigating spoofing against an old configuration
"What did this point to before?"
The question current lookups cannot answer. Enter a domain above and we will keep its history for you.
