Description of problem: Based on the soname libraries required by cyrus-imapd binary packages, it requires MariaDB connector C (the client library). The spec file requires mariadb-devel: https://gitlab.com/redhat/centos-stream/rpms/cyrus-imapd/-/blob/765456ad3e331b9e2c2c8a0cbf86e85d0db22192/cyrus-imapd.spec#L101 This is not correct, as you can read from mariadb-devel package description: "This package contains everything needed for developing MariaDB/MySQL server plugins and applications" The cyrus-imapd should require mariadb-connector-c-devel instead. The resulting cyrus-imapd packages will not be changed.

Weird, I recall me fixing that already. Thank you for reporting
