.SH NAME
qmail-newmrh \- prepare morercpthosts for qmail-smtpd
.SH SYNOPSIS
.B qmail-newmrh
.SH DESCRIPTION
.B qmail-newmrh
reads the instructions in
.B /var/lib/qmail/control/morercpthosts
and writes them into
.B /var/lib/qmail/control/morercpthosts.cdb
in a binary format suited
for quick access by
.BR qmail-smtpd .

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.
However,
.B qmail-newmrh
makes no attempt to protect against two simultaneous updates of
.BR control/morercpthosts.cdb .

The binary
.B control/morercpthosts.cdb
format is portable across machines.
