BeSender commonly appears in architectures where both shared and self-hosted mail infrastructure coexist, a pattern typical of smaller organisations and regional deployments. When domains route some mail through BeSender whilst maintaining their own mail servers for other purposes, receiving systems may encounter mail from that domain originating from both BeSender's shared IP addresses and the organisation's own infrastructure. This split architecture complicates reputation assessment and requires careful alignment of SPF, DKIM, and DMARC records across both sending paths to maintain consistent authentication.
