We want to speed the time it takes to inject mail into the qmail queue.
Currently with smtp we can only inject ~500 messages per second. To speed
this up, based on the recommendation of many on the list, I want to
implement QMTP. Will the messages queued via QMTP be stored identically to
those queued via SMTP? The messages will be received from the machine that
generates the mails via QMTP, but it will still need to send via SMTP.
Also, I know this thread has come up before, but what are the ramifications
of bypassing the concurrencyremote limit of 255? This concurrency limit
prevents us from being able to fully utilize 100mbit per network card in the
machines. Running more qmails doesn't seem to be the most logical decision
because we're already running 4 on the machine as it is (1 per nic). What
would the damages by of doubling this hard limit?
