I called build() twice for clarity. The test case fails with a single build() call. 
$msg->build(to => 'user1 <user@fqdn.org>', from => 'user2 <user2@fqdn.
+org>', subject => 'a message subject');
% ./testmail.pp
    no data in this part at ./testmail.pp line 21.

The problem is that the MIME::Lite->attach() creates a new part with no content unless the content-type is already set to multipart. This is not legal as far as MIME::Lite->send() is concerned.

I tried setting content-type but that breaks the MIME formatting of the message (all the steps that attach() is doing unless it detects multipart).
