Signature

[John G Walker]

I've been running bogofilter in Claws Mail for years. I've just moved
over to running Kubuntu and downloaded the latest version. But I'm
using the old wordlist.db from my previous installation and it's not
working. It was suggested I run bogoupgrad to upgrade the DB, so I did,
but it failed, telling me that it cannot recognise the signature.

I can find no reference to a signature in the documentation. Can
anybody explain to me what is happening?
