Susimail: Should not reformat mail; "no charset found" error + attachment fail

[Reportage]

I2P: 0.9.32-23-rc Platform: Linux 4.14

Recent changes to Susimail now reformat incoming mails according to line length, leading to display breakage when line breaks are introduced. Susimail should respect the format of mails and not attempt to reformat.

Additionally, mails created in Susimail (with attachments?) now generate a "Warning: no charset found, fallback to US-ASCII." error which results in the attachment being embedded in the mail and not as an attachment.

re: reformatting and breakage, please send or forward examples or screenshots to me at zzz@… or attach here

re: no charset warning, is that on adding the attachment, or sending the mail, or receiving the mail?
Is it related to a particular type of attachment?

Also please provide full version info from top of /logs

The pre-formatted text in the screenshot had no line breaks.

Re: charset warning, in the screenshot the warning was generated on receipt of a test e-mail sent from Susimail, in this instance without an attachment.

Susimail attachment

Thanks for the screenshots, that made it a lot easier. Reproduced here.
There was an extra CRLF before the MIME-Version header, so that and subsequent headers became part of the body. So the Content-Type and Content-Transfer-Encoding headers weren't seen, and nothing was decoded - causing both the encoding issues in the OP.
Caused by my encoding fix for subject header, which added a CRLF where there wasn't one before.
Terrible job by me not finding this in testing.
Fixed in 51c2ea9258f3502b4d630202c2eaa802edb0287c 0.9.32-24-rc
