Usually the sending (mailman to postfix to 90% of users) takes a bit more
than two hours ; yesterday it took about 6 hours. But more importantly, the
Mailman -> postfix thing took 5 hours instead of ~ 15 minutes.

Probably, yes. I don't konw if postfix can do it "on demand", though there
is http://www.postfix.org/VERP_README.html
