Infomaniak is a Swiss-based email service provider offering email hosting and messaging infrastructure for organisations and individuals worldwide. The company operates as a third-party email relay and hosting partner, serving a distributed customer base across numerous smaller and mid-sized websites rather than enterprise-scale deployments.
When Infomaniak (CH) appears in a domain's SPF record, it indicates outbound mail is routed through their servers. For email professionals, this dispersed footprint—spanning many smaller sites internationally—means sender reputation is tied to the collective behaviour of the provider's customer base; improper SPF syntax, DMARC misalignment, and recipient filtering behaviour all depend on careful configuration and the provider's operational standards.

SPF Configuration and Third-Party Sender Reputation
Including Infomaniak in an organisation's SPF record delegates outbound authentication to the provider's infrastructure. Proper include: syntax and regular verification that the include target is current are essential; sender reputation at recipient mailboxes will reflect both the domain's own practices and Infomaniak's network behaviour. DMARC alignment becomes a critical control when using a third-party relay, as misalignment leaves the organisation's domain vulnerable to spoofing and can trigger stricter filtering at recipients that enforce authentication policies.
