If there is a problem with .BR control/morercpthosts , .B qmail-newmrh complains and leaves .B control/morercpthosts.cdb alone. .B qmail-newmrh ensures that .B control/morercpthosts.cdb is updated atomically, so .B qmail-smtpd never has to wait for .B qmail-newmrh to finish.

The binary .B control/morercpthosts.cdb format is portable across machines. .SH "SEE ALSO" qmail-smtpd(8)
