     6 .SH DESCRIPTION

     7 .B qmail-newmrh

     8 reads the instructions in

     9 .B QMAILHOME/control/morercpthosts

    10 and writes them into

    11 .B QMAILHOME/control/morercpthosts.cdb

    12 in a binary format suited

    13 for quick access by

    14 .BR qmail-smtpd .

    16 If there is a problem with

    17 .BR control/morercpthosts ,

    19 complains and leaves

    20 .B control/morercpthosts.cdb

    21 alone.

    22 

    23 .B qmail-newmrh

    24 ensures that

    25 .B control/morercpthosts.cdb

    26 is updated atomically,

    27 so

    28 .B qmail-smtpd

    29 never has to wait for

    30 .B qmail-newmrh

    31 to finish.

    32 However,

    33 .B qmail-newmrh

    34 makes no attempt to protect against two simultaneous updates of

    35 .BR control/morercpthosts.cdb .

    36

    38 .B control/morercpthosts.cdb
