Environment variable POSTFIX_COMMAND_COUNTER_DATA is not set

[manuel-held]

I get this Messages if i try to use your Patterns:

[2017-07-18T13:23:59,993][ERROR][logstash.agent ] Cannot create pipeline {:reason=>"Cannot evaluate ${POSTFIX_COMMAND_COUNTER_DATA}. Environment variable POSTFIX_COMMAND_COUNTER_DATA is not set and there is no default value given."}

Logstash 5.5 / Ubuntu 17.04

I see there is a typo in line 216 of 50-filter-postfix.conf:

 match          => ["postfix_command_counter_data", "^${POSTFIX_COMMAND_COUNTER_DATA}$"]

This should read:

match          => ["postfix_command_counter_data", "^%{POSTFIX_COMMAND_COUNTER_DATA}$"]

Note the change: $ => %. Could you confirm that this works?
