error when passing outlook bounce email. attached copy of html passing about email-bounce-parser

[eliottvincent]

Hey! Thanks for using this library and reporting your issue. Two things here:

• you're passing the body as raw HTML, for optimal results this library only accepts a text body. If you use mailparser, you must use the text property from the email object. I think you're passing the html property right now. I've updated the README to make things more clear.
• there was also a bug in the code, I've fixed it in version v1.0.17. The library will not crash anymore, even if you pass HTML.

Regarding your example, I don't have it in my tests, so maybe some information will not be parsed. Maybe you can give me a copy of the text output from mailparser, so I can add it to my tests.

Let me know if thinks works for you now :)

I have released version 1.0.18 that improves parsing for the Outlook example you gave me, thanks.

Let me know if you have other examples that are not correctly parsed (this library is only a few days old 😀 )

html is parsing from this library - https://nodemailer.com/extras/mailparser/

Thanks alot @eliottvincent worked :)
Just wanted to confirm 2 things:
bounce: true --> If its a bounched email right?
data. recipient -> will always contain the bounced email?

PS: Attached is outlook text body for tests.
outlook_bounce.txt

bounce: true --> If its a bounched email right?
Remember that this library doesn't detect bounce emails. It only parses them. So you need to make sure to pass bounce emails only. I guess that you receive bounce emails on a specific email address (like [email protected]). You need to only pass emails that arrive to this email address.
If you pass other kind of emails, you may end up with misleading results. bounce: false only happens if you pass an empty body to the parser (check here).

data. recipient -> will always contain the bounced email?
From what I can tell, yes. I never saw a bounce email without the recipient email address inside.

Thanks for the Outlook body, I will update the library tomorrow!

thanks for the detail. But, the thing is, we don't have separate email for receiving bounce emails.

the field error.code ie bounce error codes, we can use to bifurcate normal vs bounce email?

[eliottvincent]

I highly recommend you to have a dedicated email address for bounces and then only parsing the mails that reach this email address.

You can use the error.code yes, but if you receive an email with 550 inside, it will be treated as a bounce, whereas it's clearly not.
What you could do is check for data.error.code + data.recipient, although you may have some false positives as well.

got it @eliottvincent thanks
