Here's the smtp log line:

How does this compare to a normal, non-VERPed delivery for this list?
I ask because Chuq Von Rospach has done some calculations on what should theoretically happen to your performance if you enable VERP, but I don't know of anyone who has actually timed the performance difference on large lists.
In any case, 2 seconds per VERP message for such a big list is too costly, so I'll just disable VERPing the normal messages for now - with the price of not being able to clean the list as efficiently as I could with the occasional VERP.
I hope this feedback can be useful, if you have scalability in mind for MM3.
This is really more of an MTA limitation, although there might be some things we can do to try to work around it with Mailman. For example, it might be faster/lower overall load on the server if we had the MTA do the VERPing for us -- we're pretty sure that's supported by some MTAs (e.g., at least some versions of Exim), and we know it's faster for at least some of them (e.g., Exim).
