Summary0003309: Malformed email Subject shows on web interface but not on Outlook

I have a case here of a billing system generating invoice emails using special UTF-8 chars on the Subject, but without any quoted-printable/base64 codification.

I know it is wrong and malformed but the web interface is showing the email correctly. When we try to open it on outlook we can't see the subject. This different is generating a bad user experience.

I was wondering if we could also make it work on Outlook 2013, interpreting it as ISO-8859-1 just like the web interface does.

If you configure Outlook 2013 with IMAP, or try Roundcube or Thunderbird, they you also interpret the special char as ISO-8859-1. Even though this is not RFC compliant.

Steps To Reproduce

I attached a file with the original email. O test it use

cat m1.eml | ssmtp

TagsNo tags attached.

Sorry, but subjects are per email standard in ASCII, so no UTF-8 without coding allowed.
Because of this, that email is invalid.
It is not even guaranteed, that it will be delivered to the recipient.
