You can't test like this. The receiving SMTP serve must be one order of magnitude faster than the one you're testing otherwise the limit might be the receiving part (supposing that the sending one is fast enough). We used to do those tests against a dual PIII 1GHz with dual ethernet epro100. On one eth was hooked the feeder, that was a quad Xeon 1GHz running an ultra-fast MT SMTP client and on the other side the was a so called SMTP black-hole able to receive 1.2 million messages per hour. Also, log must be disabled when you are testing those kind of performances since different MTA have different logging methods. IIS SMTP used to crash after 2 hour of load. - Davide - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
