Hi,
I think the mass rebuild may have taken care of this.
Unfortunatelly it was obsoleted after the mass review was complete. Both packages provided javamail and classpathx-mail would be selected unless some package required javamail directly (like jetty for example).
At least the jtnef build on July 20th built against javamail-1.4.3-11.fc18.noarch.
Yes, jtnef was build against javamail, and it doesn't need to be rebuilt, but only because jetty was in its build dependencies, and jetty requires javamail directly. Other packages might still need to be rebuilt.
