RE: multiple qmail-send
The only way you would have more than 1 instance of qmail-send is if you had more than one queue, ie a multiqueueing environment .. 1 queue for receiving, 1 for preprocessing and 1 for sending..

Re: multiple qmail-send
Please excuse my HTML side of the email. Won't happen again. I wasn't asking about qmail-remote or qmail-local. What I was asking is "Could I EVER see more than 1 qmail-send process running on my system ?". If I'm not mistaken, it's the qmail-send process the one that adds bounce addresses to the bounce directory and it's there that I haven't seen any locking system. Plus qmail-send relies on the good old select method to poll its inputs so the flow is synchronous.

This is true for qmail-local/qmail-remote, but not for the queue manager qmail-send. > and in future, please write text/plain and not text/html ACK. And you... well, I'd not answer questions here if I am not sure. No offense intended, it just confuses. For the original question: 1 qmail-send -> 1 queue You can install more than one qmail instace per machine, e. g. in /var/qmail/1/, 2/ and so on. Change conf-home and make setup check for each instance. You have multiple queues then and must find a solution to balance the load between them. -- * Henning Brauer, [EMAIL PROTECTED], http://www.bsws.de * * Roedingsmarkt 14, 20459 Hamburg, Germany * Unix is very simple, but it takes a genius to understand the simplicity.
