Which is a decent observation, for some SMTP servers.

I was thinking higher but not much higher, e.g. have a starting interval
of several minutes and increase it by a small percentage each time. If a
site is deliberately deferring mail then prompt delivery is clearly less
important to them than some other consideration, so it doesn't make much
sense to bust a gut to deliver their mail asap.

FitzRoy, Sole: South 5 or 6, increasing 7 to severe gale 9. Rough or very
rough, occasionally high later. Showers then thundery rain. Moderate or good,
occasionally poor.
