Sage is sending emails directly to my clients using my business account email address.  As Sage is not identified as a trusted sender in my SPF record, all my client invoices are therefore untrusted and going to their Quarantine/Junk mail folder.  This is to be expected.

What are the Canadian Sage Business Cloud IP ranges that I need to add to my SPF record to prevent this from happening?

Please don't suggest that my clients add the e-mail to their safe senders list.  This is not best practice.

This article from South Africa describes the issue... but I highly doubt the IP's are correct for Canada. https://www.sagecity.com/za/sage-one-accounting-south-africa/f/sage-one-accounting-south-africa-general-discussion/180639/your-email-sender-provider-seems-to-have-changed-whats-the-new-spf-records-details-we-need-to-use-to-get-this-to-work

Sage Support:  This is something that should be configured upon initial deployment.  And there is nothing found within the Sage knowledgebase.
