Many of our domains use smtp01-in.isheriff.com for their MX record, as a cloud based mail scanning server.
On of them, and only one, is returning an invalid IP address for this record, when a DNS report is run.
From running a report of degrootcarstar.com
preference = 10 smtp01-in.isheriff.com. [69.64.147.243] - THIS IP ADDRESS IS WRONG
Other DNS tools on the internet return correct IP addresses:
10 smtp01-in.isheriff.com 67.23.41.24 (no glue) - THIS IS FROM RUNNING ON INTODNS.COM, CORRECT IP ADDRESS
Why is DNSStuff returning the incorrect IP address? Is it a caching issue.
Run a report on igservices.com for comparison.. this returns the correct IP for smtp01-in.isheriff.com
At first I thought it was a problem with degrootcarstar.com DNS servers (owned by Enom), but since other DNS tools on the web report correct info, I'm not so sure
Any thought?
Thanks
