All other options are passed through to mixmaster. FILES
--configfile parameter MIXMASTER_FILTER_CONF environment ~/.Mix/filter.conf /etc/mixmaster/filter.conf The first file that is found is used. FILEFORMAT
The configuration file for mixmaster-filter is simple. Lines with whitespace only are ignored as are lines that have the hash our pound ("#") sign as their first non whitespace character. Lines are always truncated at the first hash our pound ("#") sign. The first logical line gives the filtering policy. It's either "FILTER" or "ALLOW". All other lines are taken as a list of Headers. If your policy is "FILTER" headers in your list will get removed from messages. If your policy is "ALLOW" only headers in your list will be passed to mixmaster. ENVIRONMENT
MIXMASTER_FILTER_CONF Config file to use HOME Your homedirectory. Used for finding your user configuration file. Also the default destination directory is $HOME/.Mix/ SEE ALSO
