Nope...why do you ask? >Incidentally, for us, it takes roughly 2 hours to go through the first >7K-8K of the recipients. For some reason (I'm guessing bounces), the >last 2K-3K take about 4 hours to clear the queue. So for the first 7-8k, you're sending ~1/second....not bad. You're probably right on in the last 2-3k taking 4-5 seconds per because of retries in the queue. Are you sending via CDOSYS or CDONTS? If you're sending via CDONTS, I highly recommend switching to CDOSYS. Is there any additional info in logs?
