IMAP is not working with secured connections in any form whatsoever. In looking at the logs, Dovecot mentions the following error:
imap-login: Error: Failed to initialize SSL server context: Cerror:140AB18F:SSL routines:SSL_CTX_use_certificate:ee key too small: user=<>, rip=184.108.40.206, lip=220.127.116.11, secured, session=<kcs+h8uwJtfP9OeG>
CyberPanel was installed on a fully clean and untouched image of CentOS 8. I followed the steps to add my mail domains yet Dovecot is logging this weird error.
