Simple API, Complex Emails (Jakarta Mail smtp wrapper)

NOTE: this release changes the default for DKIM signing from 'l-param' true to false. If you rely on this feature, you need to enable it explicitly. Refer to the DKIM documentation for the update.
NOTE: this breaks the API for S/MIME related builder methods. Refer to the S/MIME documentation for the new API.
Don't use this version, as the versioning was messed up here. Refer to 8.7.1 instead.
