The postfix release notes say: The Postfix-with-Cyrus-SASL build procedure has changed. You now need to specify -DUSE_CYRUS_SASL in addition to -DUSE_SASL_AUTH or else you end up without any Cyrus SASL support. The error messages are: unsupported SASL server implementation: cyrus unsupported SASL client implementation: cyrus
Fixed in rawhide in package postfix-2.3.0-2 or newer.
