Packaging 'dexpire' is less important to me since the set of INN servers I maintain changed and I no longer have a server that is perennially running out of disk space.
I know the upstream author really well, and still think dexpire could be useful for some Debian-based INN instances. If someone is interested in working on this and making sure it works well with my inn2 packaging, feel free to contact me. Bdale
