Hi everybody I like very much to use mailman, but I am always concerned about hosting the mailing list by my own website. In fact, my website host, limits the number of allowed emails to 300 emails per hour. I have a mailing list with about 70 members and right now, the average rate of email sending is one email per week, which means 70 emails per week. Of course that is not beyond the permitted limit, but I would like to expand my activities. I would like to advertise for my mailing list, so more and more members will com to this list, but there is always a big concern. if in the peak time, the users send more than 5 emails in an hour (more than 300 emails per hour), or if the number of my members goes higher, it will be very likely that some of the emails sent to this mailing list will be rejected or returned by the mailing list. Is there any throttle feature in mailman that manages the high traffic of emails in a way that I can make sure no email will be rejected or returned?

Thank you
