Service Alert: Issue with Microsoft 365 Users

We’ve been making some changes on our back-end mail servers that resulted in a number of accounts being moved to a new server.

This was done without disruption except for those who are SMTP forwarding to Microsoft 365.

This disruption was caused by Microsoft having some anti-spam ‘greylisting’ technology that caused them to greylist this new server because of the volume of emails coming from it.

To rectify this problem, we have moved all the affected accounts to another server that has been sending volumes of email to Microsoft for years, so isn’t affected by this problem.

So, many thanks Microsoft, and many apologies to all those affected by this.

Service Alert: zimbra003 Hardware Migration

Next Thursday 27th August we will be performing a hardware upgrade for zimbra003 to take it onto newer faster hardware and full SSD disk system.

Please accept our apologies for any inconvenience caused by this work.

Service Alert: MX Records Changed

We are making some backend changes that is affecting the IP addresses of our MX records.

If you use our MX records, or have delegated your MX to us, you don’t need to do anything.

However, if you have set your own MX records, please alter them to point to the following IP addresses:

All should have equal preference.

Any other MX record addresses will be gradually phased out over the next month, or two.
