qmail-newmrh - prepare morercpthosts for qmail-smtpd
qmail-newmrh reads the instructions in
QMAILHOME/control/morercpthosts and writes them into

newmrh complains and leaves control/morercpthosts.cdb alone.
qmail-newmrh ensures that control/morercpthosts.cdb is

qmail-newmrh to finish. However, qmail-newmrh makes no
attempt to protect against two simultaneous updates of
The binary control/morercpthosts.cdb format is portable
