You could use the /var/qmail/control/concurrencyremote. Set it to 0 to start quequing Use the cronjob to echo "50" > /var/qmail/control/concurrencyremote and restart the qmail to start delivering.
Now the script that will be kick by the cronjob needs to be smarter to detect when all mails are sent so you can put it back in "queue mode" Ernesto Vargas-Azofeifa Information Technology Architect OSS & LAMP stack expert ________________________________ From: F.

Just a quick question. I'm starting some tests with 2 boxes. How can I gran to have QMT in queue only mode?. QMT must only receive mails into the queue without sending them inmediately as they come. And that sending process can only be started from a call from cronjobs each 10 minutes for example. I was able to do this with exim, but I moving to QMT which is stronger. But on exim it has a queue only mode, so it only send mails each time its called from cron, and this happens every 10 minutes. This task does not disables queue only mode. One last question, how can I limit the number of conections the MTA can stablish to a remote host. Lets say there are in queue 100 mails from mymail.com host, how can I managed to have postfix only make 20 conections to any domain at a time no matter how many mails it has on its queue from that domain. Hope you can give me a hand.
