The general answere here is try and see, as you could totally test it on
your own. The certificate is read at startup and put in memory for the
rest of the execution time. Dovecot won't monitor the file for changes
on disk, as this would waste CPU cycles and make dovecot only slower for
no reason. The process (or person) that changes the file is responsible
to restart dovecot to reload the new certificate in memory.

Running dovecot 2.2, apologies if this question has been asked before:
I've done the research but couldn't find anything.
I run a server that uses dovecot as a MUA for Postfix and have a Let's
Encrypt certificate that auto-renews through certbot on Ubuntu server
16.04. Dovecot did not pick up on the new certificate for the
hostname. It did after a restart. To be clear: Let's Encrypt
overwrites the previous certificate using the same path and filename.
Am I right to assume that Dovecot needs a reload/restart after the
certificate has been renewed in order to 'pick up' on the new
certificate and if so, would I require a reload or a restart?
Thank you in advance
