            "body": "The `envelope_from` address which is used to direct bounces caught via the SenderReply exception is not guaranteed to be a valid return address. Some authentication-related checking may be necessary.\n\nWe could perhaps simply use the body `From` header's address for most SenderReply bounces (and also add `In-Reply-To` via `Message-ID`), but this won't be guarantee to  if the original message fails DKIM. We need a better method to handle bounces before or during DKIM checks.\n\nIn the following exchange, an unauthorized server (`de.andrewyu.org`) attempts to make `mail.andrewyu.org` think that it's (as in make the latter think the former is) `mail.noisytoot.org`, and attempts to send mail as `andrew@noisytoot.org` in both the envelope and `From` header. It attempts to send to the user `alwaysbounce@andrewyu.org`, which has a local delivery agent script set in `.forward` that always fails, so Postfix should be handling the bounce.\n```\nandrew@de.andrewyu.org ~ $ nc mail.andrewyu.org 25\n220 mail.andrewyu.org ESMTP andrewyu.org (Debian/GNU)\nHELO mail.noisytoot.org\n250 mail.andrewyu.org\nMAIL FROM: andrew@noisytoot.org\n250 2.1.0 Ok\nRCPT TO: alwaysbounce@andrewyu.org\n250 2.1.5 Ok\nDATA\n354 End data with <CR><LF>.<CR><LF>\nFrom: andrew@noisytoot.org\nTo: alwaysbounce@andrewyu.org\nSubject: Sending to an address that Postfix bounces, from an impersonated envelope from, and impersonated MIME From\n\nToo lazy to write content.\n.\n250 2.0.0 Ok: queued as 9372AFC0FE\n```\n\nWhen I then checked the mailbox for `andrew@noisytoot.org`, I found the bounce laying there. So apparently Postfix doesn't have a good way either.\n\nNow I'm thinking of checking SPF (alignment with envelope from) and such, but that has two problems:\n1. What if the sending user is already using a relay? We would be erroneously rejecting messages. Although most users don't do so.\n2. Even if we notice that their SPF fails, what are we going to do about it? Silently drop? Or exit abnormally so Postfix returns the email however it wants?",

My question is, how does the MTA determine the envelope sender to be valid. let me attempt to rephrase       \r\n19:37 <lunaphyte> using other values to determine where to send bounce messages is a bad, bad, idea.  please don't do that\r\n19:38 <lunaphyte> here is the actual question you need to be asking:  \"why are there bounce messages getting generated?\"\r\n19:38 <lunaphyte> define\" valid\"\r\n19:51 [AndrewYu away: sleep]\r\n00:50 <AndrewYu> lunaphyte: My (custom) mailing list manager has detected a problem in a message and needs to reject the email       \r\n01:38 <lunaphyte> what problem?\r\n01:57 <AndrewYu> Something like, \"this user does not have permission to send to this list\", or \"MIME attachments are not allowed\"    \r\n02:16 <@rob0> the MLM typically sets its own envelope sender address. That's the address that receives list bounces.\r\n02:27 <pj> AndrewYu: I would recommend that you attempt to reject the message instead of sending a bounce, otherwise your server will become a backscatter source.\r\n02:31 <pj> It basically means that your MTA needs to have a mechanism to reject the message before it's queued, postfix can do this given the proper configuration, as well as most other major MTAs.\r\n02:34 <pj> !t AndrewYu backscatter\r\n02:34 <dig-dug> AndrewYu: backscatter: Backscatter are bounces sent to innocent systems. A spammer sent email in behalf of the victim's system. Undeliverable emails get bounced to the victim. See https://en.wikipedia.org/wiki/Backscatter_(email)\r\n03:10 <lunaphyte> your philosophy is flawed.  do not accept messages and then decide if you want them.  decide if you want them before you accept them, and if not, reject them\r\n03:11 <lunaphyte> why are you attempting to write more mailing list software?  this is something that requires a comprehensive understanding of email, and how to operate email infrastructure responsibly\r\n03:12 <lunaphyte> a mailing list needs to require confirmed opt in before accepting messages from a given sender, which makes it easy to know if someone has permission to send to a list\r\n```"

When such a header is found, it should be used, instead of the program attempting to use the `dkimpy` module to re-verify DKIM.\n\nBy default, OpenDKIM only adds `Authentication-Results` when the originating domain has a \"signs all\" policy. Add `AlwaysAddARHeader yes` to `opendkim.conf` to override this. However, note that `Authentication-Results` would NOT be added to mail sent by the MTA to a user on itself, since it'd be signing rather than verifying in its pass through OpenDKIM. In this case, the `Authentication-Results` header would be completely missing, rather than some variation of `none` or `fail`. Is it safe to assert that the email comes from our own server in this situation?",
