we distribute, please contact me ... thank you)
The latest release of JavaMail (mail.jar) has these attributes in the
manifest, and can be used as an example.
I missed an attribute in the above list. Also needed is:
The manifest for JavaMail 1.2 FCS contains all these attributes, and so
is now an even better example to follow.
