This looks like you're trying to read the database file as a pickle.  I've
never used dbExpImp.py myself, so I'm not sure I can help you with that.
You might try the db2pickle.py and pickle2db.py scripts.  They are in the
Tools/scripts directory of the Python distribution.  I can send them to you
if you don't have them or you can pull them from the CVS browser on
SourceForge:

You would run db2pickle.py on your PC using the version of Python embedded
in SpamAtBay, transfer the pickle file to your server, then run pickle2db.py
there to generate a db file usable by hammie.

    Hadar> Here's an example of a failed "open" call:

    >>>> d=anydbm.open("default_bayes_database.db", "r")
    Hadar> Traceback (most recent call last):
    Hadar>   File "<stdin>", line 1, in ?
    Hadar>   File "/usr/lib/python2.2/anydbm.py", line 86, in open
    Hadar>     return mod.open(file, flag, mode)
    Hadar>   File "/usr/lib/python2.2/dbhash.py", line 16, in open
    Hadar>     return bsddb.hashopen(file, flag, mode)
    Hadar> bsddb.error: (22, 'Invalid argument')

This error isn't all that surprising.  I suspect your Unix server and your
Windows machine use different versions of the Berkeley DB library, so you
probably won't be able to simply transfer the db file directly.
