I'm using acme.sh to get my Let's Encrypt certificates. The install command is:
acme.sh --installcert -d imap.example.com
--keypath /etc/pki/dovecot/private/imap.example.com.pem
--certpath /etc/pki/dovecot/certs/imap.example.com.crt
--fullchainpath /etc/pki/dovecot/certs/imap.example.com.full.chain.crt
--reloadcmd "systemctl reload dovecot.service"
Notice the --reloadcmd.

I'm setting up certbot/letsencrypt to provide a certificate for dovecot and sendmail. Is it necessary to restart dovecot to load the new certificate, as shown in most examples I find in blogs? That seems rude to established connections. When does dovecot read the cert and key files? Once at startup or each time a connection requests SSL? Is there a preferred locking protocol when changing the two files to keep dovecot from reading one while the other is being replaced and getting a mismatched pair? doveadm reload should be enough.
