Sendmail Log Spew
Apr 21 14:26:51 darkstar sm-mta: sql_select option missing Apr 21 14:26:51 darkstar sm-mta: auxpropfunc error no mechanism available
The errors are generated from
cyrus-sasl. The messages implied the newer sendmail is configured to depend on SASL for authentication. Previous versions of sendmail packaged with Slackware never showed any such log messages.
Searching the web found many discussions but no solutions.
The sledge hammer solution was to delete related files installed by the
rm -f /usr/lib64/sasl2/libsql*
cyrus-sasl package is futile because too many packages are compiled with sasl as a dependency.
Newer is not always better.
Yet Another Example why updating computers is so frustrating.
Something always breaks. Always.
