We will be performing a software upgrade to our POP3 and IMAP servers on Sunday 16th June from 8AM.
The nature of this work requires that all the servers in the cluster need to be upgraded at the same time, this means there will be a period of around 15 minutes where POP3 and IMAP access to email will be unavailable.
We will update this post as the work is carried out
This work has been completed. (it wasn't an Exim CVE-2019-10149 upgrade, as that had already been done!)
