This warning is logged because Postfix was NOT built with -DUSE_SASL_AUTH. Source code fragment: if (var_smtpd_sasl_enable) #ifdef USE_SASL_AUTH // Code that initializes SASL support #else msg_warn("%s is true, but SASL support is not compiled in", VAR_SMTPD_SASL_ENABLE); #endif You can find the build configuration in the makedefs.out file, created in the Postfix top-level source direstory, or installed as $(postconf -h meta_directory)/makedefs.out I recommend that you use a pre-built package for your OS distribution. That will solve the startup problem too. Wietse
