We will be doing some non-service affecting work on our email (POP3 and IMAP) servers. The work involves reconfiguring how our backend mail stores synchronise mailboxes between each other. We do not anticipate this to be service affecting hence doing this work during the day.
This work is underway
Changes have been made and are under review and monitoring.
Monitoring shows no problems and a vast improvement in the speed of syncing mail between our servers.
