@lnedry Thanks for the fix in PR #58, that was some good sleuthing. Rather that using exec in a stateful way (as we had), I like the idea of making the code simpler and clearer. What do you think of this implementation that uses matchAll and the ... iterator?

exports.received_headers = function (connection) {

  const received = connection.transaction.header.get_all('received')
  if (!received.length) return []

  const results = []
  const ipany_re = net_utils.get_ipany_re('[\\[\\(](?:IPv6:)?', '[\\]\\)]')

  // Try and parse each received header
  for (const header of received) {
    for (const match of [...header.matchAll(ipany_re)]) {
      if (net_utils.is_private_ip(match[1])) continue  // exclude private IP

      const gi = this.get_geoip(match[1])
      const country = get_country(gi)
      let logmsg = `received=${match[1]}`
      if (country) {
        logmsg += ` country=${country}`
        results.push(`${match[1]}:${country}`)
      }
      connection.loginfo(this, logmsg)
    }
  }
  return results
}
