[MM3-users] configuration to send to recipients in a spread out manner to avoid being considered spam

Hi,

I s there a mean to configure the list for that emails be sent to recipients in a spread out manner to avoid being considered spam ? cause AOL, YAHOO seems to consider emails sent to recipients as spam or an "Excessively high volume of emails". there's just 40 (aol, yahoo) emails suscribed to the list.

thx.
