The Subject: says mkdir, so I'll cover that easy bit first: in the
appendfile transport which is specified by
"system_filter_file_transport", set "create_directory" (and perhaps
"directory_mode"), so that parent directories will be created for you.
The easiest way to get the month into the system filter is probably to
set an ACL variable during message reception and then refer to it in the
filter file. I _think_ the ACL variables are visible to the system
filter (but I've never checked it).
So:
warn set acl_c_month = ${extract{2}{ }{$tod_bsdinbox}}
and then just use $acl_c_month in the system filter.
Otherwise, you have to do some kind of dummy comparison against the date
and then use $1 to get the extracted field.
