Bounce: non_local_msgid is broken

[smfreegard]

I was just looking at the bounce plugin as I had a new idea for a test and I noticed that non_local_msgid:

• Is not documented
• Doesn't handle multipart messages (e.g. it doesn't check body.children) for Message-ID headers.
• Doesn't compare the Message-ID domain against rcpt_to.in_host_host OR the recipient domain against it to see if it is a local domain.
• Never returns next() when a valid state is encountered, so it appears that it would always mark bounces as invalid.

Additionally - when I gave this a quick test using the plugin test mode; it blew up immediately because I didn't surround the Message-ID in <>'s:

And when I did; the regexps pulled out the wrong values because:

domains.push(res[0].substring(1, (res[0].length -2))); is off-by-one. It would be better to use a regexp capture instead of the substring IMO anyway.

Is this now closed due to haraka/Haraka#1430?
If not, what needs to be done?

[msimerson]

It's still open. It needs a mechanism within Haraka to ask, "is this domain name local?" Because "local" domains are typically defined in plugins, it's more than a trivial task. In my case, I have "local" domains defined in smtp_forward.ini and externally (via qmail-deliverable), so Haraka accepts mails for domains it knows nothing of. Hence, the stall.

For something like this to work reliably, we'd almost need a plugin like known-senders except as known-recipients and all it would do is listen on the rcpt_ok hooks and keep a redis DB populated with domains that we accept messages for. Or something like that...

There are a couple of plugins, that if loaded (e.g. rcpt_to.in_host_list and relay) that could probably do this without a Redis DB as the domains are defined in their configuration. It would just have to skip anything else.
