Indeed, it will increase overall throughput.
However, you are sacrificing turnaround time to several minutes or more
as a result, and this from mere seconds with mm 2.1
(for that matter, with some of my lists, when I save my message in vim,
by the time I get back to the mutt index, the message has been sent,
processed by the MTA, handed out to mailman, which exploded it and sent
it back to my mailbox, so my message shows up in my index in the half
second that it took mutt to come back from vim and rescan my mailbox
If you ask me, that's pretty cool :-)
Now, I'm curious:
In your case, you get bursts of messages with lots of subscribers on
How about a list server with many lists so that you always have 50 to
100 exims running and trying to clean the queue, deliver mail, or
talking to mailman...
In that case (i.e. really loaded server), I'm not convinced that
spooling everything to disk and having exim process the message on the
next queue run is going to be that much more effective. Is it?
