The Server Extension Object (SEO) is a helper library that exposes functionality for consumption by two components:

  1. The Simple Mail Transfer Protocol (SMTP) service and the Network News Transfer Protocol (NNTP) service, both of which use SEO to create and manage event sinks, read metabase data representing event sinks, and to raise events.
  2. SMTP event sinks and NNTP event sinks that subscribe to events that are raised by, respectively, SMTP services and by NNTP services. For more information about SMTP event sinks, see Implementing SMTP Event Sinks.
