DO NOT USE, WORK IN PROGRESS, REPUTATION COMPUTATIONS ARE INCORRECT

This filter implements a reputation mechanism for incoming SMTP sessions.

The filter currently supports:

• nothing

The filter is written in Golang and doesn't have any dependencies beyond the Go extended standard library.

It requires OpenSMTPD 7.5.0 or higher, might work for earlier versions but they are not supported.

Install using Go:

$ GO111MODULE=on go get github.com/poolpOrg/filter-reputation
$ doas install -m 0555 ~/go/bin/filter-reputation /usr/local/libexec/smtpd/filter-reputation

Alternatively, clone the repository, build and install the filter:

$ cd filter-reputation/
$ go build
$ doas install -m 0555 filter-reputation /usr/local/libexec/smtpd/filter-reputation

On Ubuntu the directory to install to is different:

$ sudo install -m 0555 filter-reputation /usr/libexec/opensmtpd/filter-reputation

The filter itself requires no configuration.

It must be declared in smtpd.conf and attached to a listener for sessions to go through the kicker:

filter "reputation" proc-exec "filter-reputation"

listen on all filter "reputation"
