Still, if you have even 1% (i.e. 100) of those 10000 messages get silently blackholed because they were BCC'd, it's time to get a different bulk mail solution. But thanks for the info!

Anthony's input explains the advantage... if you use the BCC, then all emails destined for the same domain can be grouped into one connection, thusly reducing outbound mail traffic. If the emails generally are bound to different domains, then the difference could possibly be negligable in terms of the actual transmittal. Some mail servers may also be more optimized when reading a single message out of the queue and then sending a single email to 10000 people rather than reading 10000 email files out of the queue and sending each one individually. It's all a matter of where the overhead is incurred by the mail server. <><><><><><><><><><> Joshua Olson Web Application Engineer WAE Tech Inc. http://www.waetech.com/service_areas/ 706.210.0168 -- * * Please support the community that supports you. * * http://evolt.org/help_support_evolt/ For unsubscribe and other options, including the Tip Harvester and archives of thelist go to: http://lists.evolt.org Workers of the Web, evolt !
