When you say a "self-contained" javamail, you mean packaging all the 
classes needed at runtime into one JAR file? This would include a JSSE 
implementation, etc, as specified in the inetlib INSTALL file. It would 
get messy, especially when people wanted to mix and match with 
different VMs, library versions, etc.

A better solution would be to patch the manifest in the various jar 
files (gnumail.jar, gnumail-providers.jar, activation.jar, inetlib.jar) 
- - since the dependency jars have been installed to absolute locations 
by the package manager, you can simply insert a Class-Path entry in the 
manifest containing these absolute locations, and Java will locate the 
dependencies without the user having to specify a classpath explicitly.
