The bit that caught my attention is the slowness of the uid search command on some versions of Courier, which seems... related.] Perhaps this bit from the Gnus docs might help? ,---- | `nnimap-nov-is-evil' | Never generate or use a local NOV database.

In my case, both gnus-agent and gnus-agent-cache are t, but I have no idea how to set up nnimap, so I can't check any of this. One-of-these-days-I'll-really-understand-gnus-but-not-soon-ly yours, Nick
