Sorry, make that 333 msg/sec. I that case it all depends on what you do with the message. Should each message be virus scanned or even be spam scanned? Who will receive the messages? One server? How many recipient domains? How many will accept that many messages in such a short time span. Prepare for a long learning curve. p@rick > Disc IO and DNS lookup speed limit SMTP.
