Hi Bob,

The commands are the same.  I don't have any info on size efficiency for
tdb or qdbm. 

The alternate database engine code was written by people interested in
them and I've hardly used it at all.  I'm really not familiar with what
their strengths and weaknesses.  It's my impression that the other
engines have less code and result in a smaller executable and, being
simpler, run less efficiently.  

I'm posting this to the bogofilter list so that more knowledgeable
people can comment and correct any errors in what I've said :-)

Regards,

David
