}If using SSL/TLS instead of STARTTLS, substitute .startTls(true) with .ssl(true) when setting up the Mailer.
Courier supports sending S/MIME signed email through its optional dependencies on the Bouncycastle cryptography libraries. It does not yet support sending encrypted email.
Make sure the Mailer is instantiated with a signer, and then wrap your message in a Signed() object.
import courier._
import java.security.cert.X509Certificate
import java.security.PrivateKey
val certificate: X509Certificate = ???
val privateKey: PrivateKey = ???
val trustChain: Set[X509Certificate] = ???
val signer = Signer(privateKey, certificate, trustChain)
val mailer = Mailer("smtp.gmail.com", 587)
.auth(true)
.as("you@gmail.com", "p@$$w3rd")
.withSigner(signer)
.startTtls(true)()
val envelope = Envelope
.from("mr_pink" `@` "gmail.com")
.to("mr_white" `@` "gmail.com")
.subject("the jewelry store")
.content(Signed(Text("For all I know, you're the rat.")))
mailer(envelope)Since courier is based on JavaMail, you can use Mock JavaMail to execute your tests. Simply add the following to your build.sbt:
libraryDependencies += "org.jvnet.mock-javamail" % "mock-javamail" % "1.9" % "test"With this library, you should, given a little bit of boilerplate, be able to set a test against a mocked Mailbox. This repo contains an example.
