CF 4.5.x should be able to handle this volume without trouble. This sounds like a problem feeding to the mail server than it does CF itself.
Its going to back up some, sure. But not *that* bad. Are you running into issues where your mail server is maxing out the threads it has available, or is hitting a size or file count limit in the spool? Pretty sure CoolFusion's iMS SE can solve this via its CFX tag if you want to shoot the mail out in quantity, although I'm personally going in the opposite direction for a whole different set of reasons. -- --mattRobertson-- President, Janitor MSB Designs, Inc. mysecretbase.com ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Special thanks to the CF Community Suite Gold Sponsor - CFHosting.net http://www.cfhosting.net Message: http://www.houseoffusion.com/lists.cfm/link=i:4:183682 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
