Update - We're seeing improved performance on this server following works carried out today to move some mailboxes to other servers.

We're going to continue to monitor the server and will provide further updates tomorrow.

Update - The mail server is still under high load, resulting in limited and unreliable mail connections.

We are trying to increase available connections whilst also balancing this increase against the load increasing further. This balancing is only a short term solution, our System Administrators are looking at a way to reduce the load and allow all connections to be made correctly to the mail server.

The current plan to resolve this is to move specifically selected domain's mailboxes off the mail server and then on to another mail server which should reduce the load dramatically. These domains have been selected as they are the largest legitimate consumers of resources on the server and limiting the total number of domains moved makes the process as fast and efficient as possible.

These migrations have been completing steadily and we expect the last ones that will be required to be finished by the end of the day today, though performance has already been improving once the migrations have finished this will free up even more resources in itself and we are confident that should resolve the issue almost completely and further impact should be minimal if it's present at all. Our System Administrators have already taken action identifying and disabling any services that can be currently considered extraneous.
