  Description     : 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. The exporter also connects to
Postfix's admin Unix socket to obtain metrics about messages currently
in the queue.

This package is useful for monitoring the health / throughput of Postfix
mail servers, since Postfix does not natively offer a Prometheus metrics
endpoint. This exporter has a slight advantage over the mtail log parser
approach, since it connects to the Postfix admin socket also.

I plan to maintain this with the long-term assistance of the Debian Go
packaging team. Benjamin Drung (bdrung@debian.org) will sponsor me for
the upload of this package.
