My company routinely sends out large mail blasts to our subscribers using CF and IIS SMTP. CF seems to do it's job quite nicely, and we can see the messages moving from the CF spool into the IIS Queue, but then things bog down. IIS seems to be sending out 3-5 messages/second, which is painfully slow for large volumes of mail.
We are doing this on a Win Server 2003 with CFMX 7. They are both on the same box, but we see no problems with CPU or RAM utilization (not even close). We have looked at IIS SMTP settings and tried various combinations (# messages per connection, etc); nothing seems to help. Any ideas? Is 3-5 messages/second expected performance? It seems very low to me, but I'm not sure how to improve things at this point. I've heard that you can have CF write messages directly to the IIS mail pickup folder, but since mail leaves the CF spool quickly I presume that's not the bottleneck.
