I know some of you guys use postfix. How do you monitor how many messages are in the queue? Outbound connections? I need to keep track of this to figure out when stuff sits in my queue too long, and when I need to add capacity. Basically, I just need to make sure the messages go out as fast as they come in. This is all for stock price alerts for our clients, so it's very time sensitive. More than a 10 minute delay is too much, and the sheer volume of alerts is absolutely crazy. It's working fine now, after a switch from qmail to postfix, but the demand is growing fast. Jay
