Situation



How long does it take domain changes to take affect? When will a new email address added be able to send and receive emails? When do custom filters and sender list start allowing/blocking?

F.Q.A


 

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
