In the past we used a send connector to send to an organization we work with but now that is changing and I have removed the send connector. The problem though is that the MX records do not seem to be updating to the next MX records.
If I do a MXLOOKUP internally it has the wrong information but if I do an MXlookup on mxtoolbox.com it has the correct information.
Any suggestions on updating the internal records?
