I think that this would require a second MTA instance -- the first instance of sendmail (or whatever MTA) would simply take everything that Mailman gives it and then store that in the queue. This would be different from a normal sendmail (or other MTA) configuration, where immediate delivery would normally be attempted. Then, additional queue runners are called to start processing that queue and pushing those messages out, but they go through an additional instance of sendmail, where the throttling milter is used. You would also need to make sure that the first instance of sendmail (or whatever MTA) is not configured to generate Delivery Status Notices (DSNs) for delayed messages, because you know for a fact that some messages are going to be delayed for a significant period of time, and you don't want those kinds of warnings clouding the picture for Mailman. And I'm sure there are other factors or issues to be considered, although I haven't thought of any others off the top of my head. This is a complex problem, which is why Mailman has not attempted to deal with this issue in the past. If you're running a large list, I still firmly believe that you should be hosting that list at a provider where you are not required to do any throttling. If you do have to do throttling, then you're hosting your list at the wrong place. -- Brad Knowles, <[EMAIL PROTECTED]> "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." -- Benjamin Franklin (1706-1790), reply of the Pennsylvania Assembly to the Governor, November 11, 1755 LOPSA member since December 2005.
