SimpleRelay is a self-hosted, multi-tenant SMTP relay with a web dashboard, routing outbound email through multiple upstream SMTP providers based on sender address, with DNS validation and per-sender access control. It's aimed at organizations wanting centralized control over outbound email routing across several providers instead of hardcoding one provider per application.
