 Name

    checkaddr - MMDF address verification program

 Syntax

    /usr/mmdf/bin/checkaddr [ -w ] [ addresses... ]

 Description

    The checkaddr program is used to check the validity of an address within
    the local mail system (MMDF).  checkaddr can be given addresses either on
    the command line, one address per argument, or a list of addresses can be
    given to checkaddr on the standard input, one address per line.  The
    latter mode is used for checking the addresses in a mailing list as in
    checkaddr < mailing-list-file.  checkaddr announces each address on a
    separate line and follows the address with its status (normally ``OK'').
    checkaddr uses submit(ADM) to do the address verification.

    If the -w option is given, checkaddr causes submit to generate a detailed
    submission tracing.  This can sometimes be useful to help find problems
    in alias files or mailing lists.
