  • Should you wish to use a wireless network for client machines we insist that this is of Commercial Class and not a consumer variant.
  • Within your office you could have many different services running which utilise your office network as well as your broadband connection.
  • If you are using a VOIP service for communications then a separate broadband connection is recommended for it’s sole use. If this is not possible, Quality Of Service (QOS) will need to be setup to reserve connection speed for certain services, ensuring enough bandwidth is reserved for each software user.

Email Whitelisting & SPF / DKIM Records

Email Whitelisting
In order to ensure you receive any email correspondence from our Support and Marketing Teams direct to your Inbox, please add the following domains to your receiving Email Server Whitelist:

SPF Record
Dezrez requires a Sender Policy Framework (SPF) record with our specific mail server information to be authorised and identified to send email on behalf of your domain.

Don't have an SPF record?

If you do not have an SPF record for your domain please refer to the Sender Policy Framework website for more information.

Already have an SPF record for your domain?
No problem. You simply need to add the SendGrid include mechanism lookup into your existing record before ~all :

DKIM Record
Your email provider may require the use of DKIM records to authenticate email sent from within the Rezi software.
If this is required, please contact our Support Team and we will provide you with the necessary records to add to your domain's DNS
