[Mailman-Users] Mailman : too fast when small ressources, how to make it slower

[Kevin]

Hello,

I use mailman for around 3000 subscribers on a small VDS (virtual server 
under Virtuozzo).
I've configured postfix to fork no more than 10 times to avoid aving to 
many process (no more than 128 ... or my system become instable).
But It seems mailman is too fast to generate mails so that it use a lot 
off kernel memory, too much for my VDS which cause a non sending of many 
emails, memory is not allocate by Virtuozzo to my Vds.
Of course I can't reconfigure Virtuozzo parameters, so here is my point :

it there a way to configure mailman to send emails to a list slower than 
normal ?

I was thinking of sending mails per packets, for example 100 by 100, in 
a predifined period of time, but I haven't found how to configure 
mailman for that ...

I'm quit new in mailman by I haven't found the answer yet, usually 
people want that mailman generates and sends mail faster ... That is not 
my case :(

Thanks for your precious help.
