Well, if the user insist on deleting his spam folder *and* has a client
that insists on using a trash folder (I tell people using my setup to
turn off trash folders) then there may be a problem. But my plugin has
an option to ignore trash folders.

FWIW, I just put this up a few hours ago:

You could simply log the signature and do signature-based training.
Actually, somebody has done exactly that with logging to mysql. Search
the list archives to find the variation of the dspam plugin doing that.

Sounds almost like the dspam plugin needs to grow a plugin system itself
to support all the backend configuration and various dspam installations
like with/without signature in uid etc. You guys want to pool and buy me
to do that? ;)
