Many email providers now apply spam detection filtering to incoming email messages and, increasingly, will just file any messages it thinks are spam away and not make them visible, or at least not prominently so, to the intended recipient. One of the tools in the spam detection armoury is to check whether the server which sent the email is associated with the domain name of the "from" email address. If the sending server is not associated with the email address being sent "from", then it may well be an indication of spam.

When you send email to students, staff or parents from your CHQ site, the email is sent using our own email servers, which of course by default are not associated with your school domain in any way. This means that emails sent stand a chance of being intercepted as spam, especially by services such as, and others.

Fortunately, there is a way to "authorise" the CHQ email server to send your emails for you. It's called Sender Protection Framework, or SPF, and it is a method of you as owner of your school domain adding our server as an approved sending server.

We strongly advise all schools add or amend their domain SPF record to include the CHQ email server as an approved sender.

For customers on our UK hosted solution at, emails are sent by a server on the range of IP address

For customers on our Singapore hosted solution at, emails are sent by that same server (IP address

CHQ cannot provide support or training about SPF or how to configure your DNS entries; please refer to your IT department or email service provider for this information, or look on-line.

For your convenience here are a few links that might be useful (CHQ is not responsible for the content of theses web pages, or their availability).
