Hi,
Thanks for the reply.

The other way is to let the cron job spawn new processes (up to a
limited number of child proceses) as long as there are mails to send.
These child processes runs as long as there are mails to send, then
they die. The cron job will then mostly do process controll/start new
processes.

How can I do this. I'am thinking to use a PHP Script?

If N is the number of mails you can send per cronjob in 10 minutes,
then run 100 000/N cron jobs.
You will be very happy if you also add som kind of "sleep" (for a
growing number of seconds) to the cronjobs when there are currently no
more mails to send. Otherwise you will end up with a very annoying CPU
load.

That ought to do the trick.
