NAME
    ./genfilter.ps1

SYNOPSIS
    Generate a mail filters file for blocking Evil Recruiter Spam


SYNTAX
    ./genfilter.ps1 [[-list] <String>] [[-format] <String>] [[-outfile] <String>] [<CommonParameters>]


DESCRIPTION
    This PowerShell script will generate either Gmail style mail filters (in XML format)
    or CSV style mail filters (perfect for ZOHO and perhaps other mail providers)

    By default, the "list.txt" file will be consumed and a mailFilters.xml file will
    be generated. This is ideal for Gmail filter imports. You can optionally provide
    a different file name or path, a file format (currently "csv" or "default" which is XML),
    and and output file path/name. The default output file is mailFilter.<file extension here>,
    such as mailFilter.xml or mailFilters.csv
