spring-boot-james-smtp-server

Simple SMTP Server using Apache James (Netty) and Spring Boot which just logs sender, recipient and size for every message.

It is very easy to use an existing Apache James Hook or implement your own Hook. Also see https://james.apache.org/server/dev-provided-smtp-hooks.html

mvn spring-boot:run
