NC027: Mail server queue clearing

2 November 2015 10:05:03 +0000

A configuration change on server NC027 (the mail server) over the weekend to once again introduce virus scanning has, as on previous occasions, overloaded the server. We made this change over the weekend after earlier doubling the capacity of the server and making other changes recently that should have seen a significant increase in server performance. Indeed, testing over the weekend showed a significant improvement over previous attempts to introduce virus scanning.

The result of this is that incoming emails have been delayed this morning, including messages between accounts on the same server. Therefore we have again reversed this configuration change and the mail queue has begun clearing. We hope that it will be clear within the next hour.

We apologise for this inconvenience.
