Signing E-Mails with smime

[ASchmidt84]

Is it possible to sign an e-mail with an S-MIME with an official certificate?
And if yes how I have to do this. And if not, would be their an other way to sign the mail?
Thank you.

Hello @IntelligyScience
We do not provide an easy way to sign an email using S-MIME. I believe it's possible to use this library to sign an email with JavaMail: https://github.com/markenwerk/java-utils-mail-smime

How do you sign the Email instance using this library?
