Creates a MIME encoded message with headers given by the first
argument, and a message given by the second.
Optional attachments can be specified in the third arrayref argument.
+Whether to include the date in the header is the final argument; it
+defaults to true, setting the Date header if one is not already
+present.
+
Headers are passed directly to MIME::Entity::build, the message is the
first attachment.
