Sending out thousands of emails at once and need them delivered faster than the CF spool is doing

I'm using Coldfusion 9 standard and my mail server is postfix

What I'm doing is sending around 1,500 emails at once (many times per day), using cfmail, and they are time sensitive so I need them to go out all at once at the same time if possible.

Right now I have mail spooling enabled in the CF admin and the server interval is set to check every 1 second.

I'm using spooling so my users dont have to wait while messages are sent after they submit my sending form.

Is there any way to figure out how many messages CF sends at once when using the spooler?  Can I up that value?  

Any recommendations on what I need to do here would be great.

depending on the resources available you could try increasing the number of processes allow to run at once


default_process_limit (default: 100)
The default maximal number of Postfix child processes that provide a given service. This limit can be overruled for specific services in the master.cf file.

master.cf

# ==========================================================================
# service type  private unpriv  chroot  wakeup  maxproc command + args
#               (yes)   (yes)   (yes)   (never) (100)
# ==========================================================================
smtp      inet  n       -       n       -       -       smtpd




       Process limit (default: $default_process_limit)
              The maximum number of processes  that  may  execute
              this  service  simultaneously.  Specify  0  for  no
              process count limit.

              NOTE: Some Postfix services must be configured as a
              single-process  service  (for example, qmgr(8)) and
              some services must be configured  with  no  process
              limit (for example, cleanup(8)).  These limits must
              not be changed.

These are probably the services that need to be changed.


smtp      unix  -       -       n       -       -       smtp
relay     unix  -       -       n       -       -       smtp
