ecoding? errors with outlook, gmail #13

Closed mathe42 closed 2 years ago

mathe42 commented 2 years ago

v0.16.0 made additional encoding errors it seems. Added original message content at https://gist.github.com/xCykrix/00a71d6aaf400630910ed3e0de90b17b#file-new-original-message

Creating my own inbox with Ethereal and sending it via Ethereal gives the expected outcome (also sent inbound to the account via my SMTP server), but if I send it to Gmail or Outlook it has encoding errors. 0.16.1 did not resolve the issue. I'll try to send it via Gmail SMTP to see if perhaps it will have a different result.

Also: deno 1.21.0 (release, x86_64-unknown-linux-gnu) v8 10.0.139.17 typescript 4.6.2

Alright. So I dug into it a bit more and came up with basically nothing of use besides "0a" which is what wants to appear now. Ethereal renders it correctly, but even Gmail to Gmail (used my girlfriend's Gmail to receive and mine to send) has the faulty encoding. So that pretty much narrows out it being my SMTP server causing an issue.

EDIT: The difference I found now is that even 100% minimization (1-liner HTML) now no longer works for me.

mathe42 commented 2 years ago

Lol I could now reproduce it.

It has to be the gmail...

gmail -> gmail creates problem gmail -> gmx.de creates no problem gmx.de -> gmail creates no problem

Very strange...

mathe42 commented 2 years ago

I'm stupid. One of the errors wasn't fixed...

mathe42 commented 2 years ago

~0.16.2 should be fine now!~

mathe42 commented 2 years ago

0.16.3 should be fine now!

xCykrix commented 2 years ago

@mathe42 One last slight little dumb one. Gmail is working perfectly, but Outlook (Desktop&Android) has a trailing "a" at the end for some reason when using the HTML at https://gist.github.com/xCykrix/00a71d6aaf400630910ed3e0de90b17b#file-sent-html

If I beautify the HTML it works as intended, so I'm assuming it is still just one oddball in encoding.

mathe42 commented 2 years ago

Outlook has a Option to show the raw Email could you share that?

mathe42 commented 2 years ago

useing android Outlook I could not reproduce it...

xCykrix commented 2 years ago

Added to the gist. https://gist.github.com/xCykrix/00a71d6aaf400630910ed3e0de90b17b#file-raw-content-mht

It is right near the end at a comment. So confused as to where it comes from.

mathe42 commented 2 years ago

I release 1.16.4 this should not fix it. But could you try :D. Found a stupid bug (that codepath should not be used so this should not have any effect)

xCykrix commented 2 years ago

Unable to reproduce it now. Not sure what you changed but it worked.

mathe42 commented 2 years ago

ok lol.

I will close this. Then the error has to be some line ending bugs or so...
