The -d27.3 debugging switch causes each path for a possible .forward file to be printed before it is tried: forward: trying file Here, file is each file in the path of files declared by the ForwardPath option (ForwardPath). The -d27.3 debugging switch also causes sendmail to trace its wait for another alias rebuild to complete (Section 12.5.1). First sendmail prints the database type (such as hash ) and filename for which it will wait: aliaswait( dbtype:file ) If the database is not rebuildable (as would be the case with a network database type, such as nis , nis+ , or hesiod ), the -d27.3 debugging switch causes the following to be printed: aliaswait: not rebuildable If the file specified doesn't exist, the -d27.3 debugging switch prints: aliaswait: no source file The -d27.3 debugging switch also causes sendmail to print an error message if there was a read error while processing a :include : or .forward file: include: read error: reason here |
