Nice idea, Ernesto.
You can easily stop and start the send process with
# touch /var/qmail/supervise/send/down
# rm /var/qmail/supervise/send/down
but this would stop local and remote delivery.
I think the important question here is, why do this? I'm guessing that
the idea here is to keep the sending process from being blacklisted.
I would love to see a (more extensive) throttling feature added to the
qmail-remote program. I think it would be relatively simple to add a
parameter that would limit the rate messages are sent a) from a given
account/user, and b) to a given MX server. This rate would be global,
and might be tailorable by account or destination server. If someone
would like to work on developing such a feature, please subscribe to the
devel list and perhaps we can make this happen.
Limiting the number of connections qmail-remote makes to a given host
(which would be a nice feature) is presently not trivial to do. I expect
you could use iptables to accomplish this. I'm not sure though how
qmail-remote would behave when a connection is blocked this way.

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"

*Subject:* [qmailtoaster] Queue only mode and call from cron
Hello everyone.
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 <http://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.
