I agree that throttling would be a good thing to have, both within Mailman itself, and also within the MTA. However, we don't have any control over the MTA, so all we can worry about is what happens within Mailman.

Alternatively, this should be added as a Request For Enhancement via the tracker at http://sourceforge.net/tracker/?group_id=103atid=350103, and people just have to hope that someone who is hacking on the code decides to pick up this issue at some point in the not-to-distant future. -- 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 SAGE member since 1995.

There's a note in one of the source files, I think it's Runner.py, something like this is where you could implement things like throttling.

With all respect to Stephen, who knows this topic way better than I do, I have to disagree with this approach. I would think that throttling is an MTA issue (in this case Exim). Given that the MTA will control the rate of ALL messages from the system, not just those that are generated by Mailman. That might not be an issue in this situation, but generally it is true. Fixing throttling in Mailman would still potentially leave an admin open for capacity issues generated by users or other email generation applications. However, fixing it in the MTA, the last step before leaving the box, would mitigate the issue for all email from the system (Mailman or not). Just a thought.

[Mailman-Users] sending mail to members in batches
Hi I'm wondering if there is a setting in mailman to send mail out to members of a list in batches - for example send 100, wait 30 seconds, send to the next 100, wait 30 seconds, and so on. The problem is we've got a list with 1000+ members, but there is a per-hour outgoing mail limit of 600 (and we'd rather not change it). This is a cPanel install (and from what I've heard, they distribute a custom version of mailman), but they don't have any settings I can change. I've seen the Exim tweaks and will be looking at implementing them, but I'm not sure if it'll be enough. I've had a look through all of the archives, and googled until my fingers bled (ok, not really), and the only thing I've found was a reference to what I think is another customised version of mailman or something completely different (it mentioned settings that I can't find anywhere). Any help appreciated, and if this is in an FAQ somewhere, then I do apologise.

Nope. See http://www.python.org/cgi-bin/faqw-mm.py?req=showfile=faq04.051.htp. This is a cPanel install (and from what I've heard, they distribute a custom version of mailman), but they don't have any settings I can change. Well, cPanel is rather problematic.
