Synergy Wholesale appears most commonly in SPF configurations alongside Microsoft 365, indicating it frequently serves as an on-premises or hybrid mail routing layer for Australian small businesses using cloud-based email. This creates multi-include SPF records where Synergy Wholesale entries sit alongside Outlook and Exchange Online mechanisms. For mail administrators supporting Australian businesses, this pairing signals a small organisation running both local mail infrastructure and cloud email services, which affects SPF record complexity and DMARC policy enforcement on the sending side.
