The problem is definately dspam. We have been through their code.
The new version is much, much better than the older one but I am sure
there is more work to be done.

The first version we installed suffered from a well known problem:

It would use smallint/bigint but would not cast or quote the
where clauses and thus PostgreSQL would never use the indexes.

It was also missing several indexes on appropriate columns.

We offered some advice and we know that some of it was taken but
we don't know which.

Sincerely,

Joshua D. Drake
