go-check-smtp

Build Status

go-check-smtp is a simple drop-in replacement for check_smtp in nagios-plugins distribution written in Go.

Motivation

I think check_smtp with STARTTLS seems to be broken because check_smtp does not trigger warning or critical even though SMTP server returns 4xx/5xx.

My SMTP server speaks HAProxy's proxy protocol to receive connections from AWS's ELB so I also need check_smtp with proxy protocol support.

Installation

Download from releases.

Or

go get -u github.com/nabeken/go-check-smtp
