FAQ: Why does it take so long for these changes to take effect?
Mail Transfer Agents (MTA) cannot access in real-time the same database where the data in question (user account data, etc) is stored. They need static lookup files that are compiled on a periodic basis in order to work. These files cannot be recreated too frequently because doing so causes a drop in MTA performance, as all the SMTPD processes
need to reload upon any change.
* Will need to propagate through all of our systems. If testing please wait a minute or two.
** These updates are done at the top and bottom of the hour but could take up to an hour after changes to be fully propagated
