Modern anti-spam measures, especially google's, have gotten fairly
non-deterministic, at least to outward inspection.  It is especially
difficult to reason about delivery timing.  For example, the list server
may well have had the notice in queue trying to get google to accept it
for a number of days.  Google is known to hold things for several days,
progressively showing them to a few more people, until it decides
whether they're spam or not.  A single-address notice wouldn't seem to
be a candidate for that behavior, but _I_ wouldn't bet any money against
google comparing such a single-address message against other singles
that were statistically (or machine-learning-y) similar.

Yes, two weeks seems long, but if a number of list posts were queued up
on the list server not getting delivered to you for some days, and
google deferred some of them, and google deferred the notice, and google
held the notice after accepting it, that could actually pretty easily
add up to more than two weeks.

Mailman sends the notice at the point it makes the decision.  There are
some knobs for how many bounces over what time period result in action.
