Not mentioned, but necessary information in this sort of case:

- "horsepower" of your platform (CPU, speed, memory, disk space)

- Upstream bandwidth, and whether it is throttled.

- What connections or message-size limits (if any) you are configured for

- What sort of resource load is SpamAssassin showing?

Bugs that might strike at 2,000 /hr should have already surfaced at
1000/hr, so
one suspects a simple shortage of resources (external to Exim, probably).
