First of all, you shouldn't only write to one person. The mailing list should be
used to allow everyone to participate this discussion.

I think there are two possible solutions for this problem:

1. Start a Java Specification Request (JSR) that integrates ACLs into the non
provider specific Java Mail API.

2. The author of Webmail has to add an abstract layer that implementations uses
Sun provider specific or GNU classpath specific API for ACLs. This can be done
through the GOF Design Pattern "Bridge".

This are just my two cents that lead to a functional implementation that can
base on commercial and free implementations. It must simply work for the normal
groupware user.
