[...] To extend the validity time of a self-signed certificate for Dovecot, you can use the following command: openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout /etc/ssl/private/dovecot.key -out /etc/ssl/certs/dovecot.pem The -days option specifies the number of days that the certificate will be valid. In this example, it is set to 3650 days (10 years). You can adjust this value as needed. CER> If there is a man page for that configuration file, please point CER> me to it ;-) You can find more information on how to create self-signed SSL certificates using OpenSSL in Dovecot’s documentation.
