From the French "Courrier" (mail)

A Kotlin/JVM wrapper around the JavaMail API

You can import Kourrier directly with the jar files, or using your favorite dependency manager with the Maven Central repository:

<dependencies>
  <dependency>
    <groupId>com.notkamui.libs</groupId>
    <artifactId>kourrier</artifactId>
    <version>0.2.2</version>
  </dependency>
</dependencies>

repositories {
  mavenCentral()
}

dependencies {
  implementation("com.notkamui.libs:kourrier:0.2.2")
}

repositories {
  mavenCentral()
}

dependencies {
  implementation 'com.notkamui.libs:kourrier:0.2.2'
}

(In case you're using it with another language than Kotlin -- i.e. Java --, make sure you include kotlin stdlib too)
