are you sure? What is the refresh time? Instantly or with some delay? Have you
tested what happens if I install new key, but I delay installing correct
certificate? Does postfix keep the old key+cert or stop using any cert because
the new key is not correct for the current(old) certificate?
On my postfix 2.9.6 on debian wheezy 7 and postfix 2.11.3 on debian jessie 8 I
have to reload postfix. Postfix can use the same key+cert even if I deleted
these files.

/*
If you run certbot often enough to renew well in advance of expiration,
reloads of Postfix are unnecessary, and just needlessly interrupt orderly
processing of email by the queue manager. Usually the new certificate will
be automatically in use within "$max_idle * $max_use" seconds, and typically
sooner, because processes either idle out quickly or reach the re-use limit
quickly, handling $max_use connections that are exactly $max_idle apart is
rather unlikely By default that's 10000 seconds or just under 3 hours.
