	If switching filesystems is an option, you might want to take a 
look at Veritas VxFS.  It's a commercial replacement that should be 
more than enough for your needs.  I've had experience with SGI XFS 
(on real SGI hardware), and other journaling filesystems, as well as 
other extent-based directory-hashing filesystems, and VxFS beats 
everything else I've seen -- hands-down.

	If VxFS isn't an option, keep an eye on ZFS for Solaris 10.  I've 
heard some really good things about it.

	Otherwise, you may be forced to have multiple Mailman 
installations, each covering a subset of your 15,000 lists.  Or, you 
may need to come up with a hack to implement a hashed directory 

	There is an old patch at 
which sounds related according to the description, but the comment 
from Barry indicates that something similar has already been applied 
to the code, which is why this patch was closed.
