To Reproduce
Steps to reproduce the behavior:

1. git clone https://github.com/dcdh/quarkus-sample-email-app.git
2. update application.properties to define the quarkus.mailer.password= corresponding to the api key used in sendgrid
3. update graalvm path in build_native.sh to your local graalvm path
4. run build_native.sh
5. start the application by using ./target/quarkus-sample-email-app-1.0-SNAPSHOT-runner
6. use curl to call the endpoint sending the email curl http://localhost:8080/simple

Configuration

# Add your application.properties here, if applicable.
quarkus.mailer.password=**sendgrid api smtp key**

Hey @dcdh, I looked at the configuration file and I think you are missing

quarkus.ssl.native=true

can you try adding the configuration option. For more info on how to set SSL in native images see our guide: https://quarkus.io/guides/native-and-ssl-guide

@gsmet @cescoffier should we activate activate ssl for native images when quarkus.mailer.ssl is set to true? Spoke too early, maybe it is not possible since SslNativeConfigBuildItem is a SimpleBuildItem. We could perhaps document that quarkus.ssl.native config option is required and has to be set to true when quarkus.mailer.ssl=true in the mailer guide.

@machi1990 I confirm, adding quarkus.ssl.native=true in application.properties fix the problem.

Thanks a lot for your help.

Document this behavior into https://quarkus.io/guides/sending-emails may be a great help.

@gsmet I'll like to finish this work :-). Let me prepare something.
