letterparser's Issues

Broken links

Hi, the parse works fine but it turns '' to ' ' ('' to space).
Later the spaces turn into "%20" in the browser and links fail, images that contain _ fail to load due to incorrect url
Exemple:
https://google.com/abc_de
after extracting
https://google.com/abc de
rendering on browser
https://google.com/abc%20de

Using letterparser with nextjs ends with SyntaxError: Cannot use import statement outside a module

Server Error
SyntaxError: Cannot use import statement outside a module

This error happened while generating the page. Any console logs will be displayed in the terminal window.

Handling of Multipart message fails

Hi,

If a send a simple multipart message and catch it with your micromta code - then pass it to letterparser It fails to decode the parts...

Here is the incoming multipart

{
  recipients: [ '[email protected]' ],
  sender: '[email protected]',
  message: 'Content-Type: multipart/mixed; boundary="--_NmP-79d22631bd047a69-Part_1"\r\n' +
    'From: [email protected]\r\n' +
    'To: [email protected]\r\n' +
    'Subject: New Subject\r\n' +
    'Message-ID: <[email protected]>\r\n' +
    'Date: Tue, 13 Oct 2020 19:12:21 +0000\r\n' +
    'MIME-Version: 1.0\r\n' +
    '\r\n' +
    '----_NmP-79d22631bd047a69-Part_1\r\n' +
    'Content-Type: text/plain; charset=utf-8\r\n' +
    'Content-Transfer-Encoding: 7bit\r\n' +
    '\r\n' +
    'More words I have an attachment\r\n' +
    '----_NmP-79d22631bd047a69-Part_1\r\n' +
    'Content-Type: text/plain; name="c:/temp/foo.txt"\r\n' +
    'Content-Transfer-Encoding: base64\r\n' +
    'Content-Disposition: attachment; filename="c:/temp/foo.txt"\r\n' +
    '\r\n' +
    'U29tZSBzbWFsbCB3b3JkcyB0byB0ZXN0IGF0dGFjaG1lbnQ=\r\n' +
    '----_NmP-79d22631bd047a69-Part_1--'
}

If I add some debug I can that for some reason in line 43 of parser.js you do

    var split = value
        .toLowerCase()

which then ends up with parameters['boundary'] being all lower case which for the message above you can see is not the case... so I'm not sure why you make it all lowercase ?

However If I remove that then I do get a return object with multiple "body"s - but they are both empty strings.... so something else is also not working...

Many thanks

PS the email above was generated using nodemailer, in case that matters.

Multipart type lacking boundary at line 1

While looking for an example of #8 I came across this issue.

I get the error Error: Multipart type lacking boundary at line 1 when parsing this email.

German Umlauts (Ä, Ö, Ü) in attachments filenames not parsed correctly

if we have a German Umlaut in the attachments filename, the letterparser transforms the attachment like this:

=?iso-8859-1?Q?Pr=FCfbericht.pdf?=

it was a PDF File with the name Prüfbericht.pdf

let me know if you need anything else

Thanks!

Unable to parse emails from yahoo mail

Getting the below error while parsing email from yahoo.

Comma in names breaks parsing RFC5322 entries

e.g. when I have this in my To header:

This ends up getting parsed by letterparser like:

To: undefined <"last>
To: first (test) <[email protected]>

ECMA module

Hi :)

Would it be possible to have this as ECMA module?

My Angular CLI is complaining: https://web.dev/commonjs-larger-bundles/

Thanks for considering :D

Error when parsing strange Content-Type header

letterparser currently cannot parse this Content-Type:

Content-Type: text/plain; charset = "utf-8"

This Content-Type is found in email sent by QQ Mail SMTP server (but don't know how to trigger that exactly)

I checked the code and after const parameterSplit = parameter.split('=');, letterparser trimed the header name, but didn't trim the header value, causing the fail

Can letterparser be used on the frontend?

I'm looking for a solution that would enable email parsing on the client side. Is it possible with letterparser? Should I look elsewhere? Do you believe some additional work could enable it (which I would then be inclined to try to bring into the project)?

Thanks

Quoted-Printable not being handled in Header by LetterparserMail

Given this:

          const result: LetterparserMail = extract(block.Data);
          const raw: LetterparserNode = parse(block.Data);

result.from shows

address: "[email protected]"
name: "=?utf-8?Q?jmetertester06@xxx=2Elocal?="
raw: "\"=?utf-8?Q?jmetertester06@xxx=2Elocal?=\" <[email protected]>"

The name is not being converted from Quoted-Printable per the Content-Transfer-Encoding

Base-64 parsing error

Thanks for an interesting project.

I had trouble parsing a message with a base64-encoded attachment - it was throwing an exception about the length not being a multiple of 4. What worked for me as a quick hack was to strip line breaks from the string before decoding it.

That's probably not a full fix, so I've not created a PR, but perhaps it's helpful.
