The mailing list for listmasters using Sympa

[Alfredo Cuaresma <address@concealed>]

Hello,

i'm testing Sympa, phplist, mailman and others, and i have an issue to solve: my ISP doesn't allow me to send more than 500 emails/hour, and i have mailing lists of 10.000 users. Is there any "thottle option" in Sympa to configure it for sending for instance 500 mails/hour maximum, queuing the rest for the next hours?

Thanks.
