Are you running an MTA? If so which one? Couple of things to check: If running exim or similar it will only deliver a certain number of messages simultaniously. You can check the queue to make sure the messages aren't sticking in the queue, a queue-runner should execute every 15 minutes or so and pick these up. Note with procmail that you do not need to lock a maildir, :0: can be replaced with :0 if memory serves. I usually shovel messages direct to maildirs with safecat and that goes extremely quickly but each to their own. regards, kerry.
