Prometheus exporter for Postfix mail servers

 Prometheus exporter which scrapes the systemd journal of Postfix MTA daemons
 to expose various metrics such as SMTP connection counts, message delivery
 statuses / delays etc. This exporter has a slight advantage over the mtail
 log parser approach, since it also connects to the Postfix admin Unix socket
 to expose metrics about messages currently in the queue.
