This file is used as the default for other hostname-related control files. Comments are allowed in .IR badmailfrom , .IR locals , .IR percenthack , .IR qmqpservers , .IR rcpthosts , .IR smtproutes , and .IR virtualdomains . Trailing spaces and tabs are allowed in any control file. The following table lists all control files other than .IR me .
