Emergency Upgrade – SMTP (Array01 EasyHTTP)

Our software vendor for MailEnable (who provide our SMTP server software) has alerted us to a vulnerability in several releases of their software. We will take immediate action and install these patches.

As a result this will stop email flow for around 5 minutes while we take the service off line to perform the upgrade.

This is for your own protection and we will advise once complete. We apologise for any inconvenience this may cause.

 ***UPDATE***

This work is now complete and the platform version has been updated to 7.07.
