            Bug ID: 448029
           Summary: Spam false-positive, because KMail mis-parses some
                    links
           Product: kmail2
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org

Link looks alright in the message view

SUMMARY

KMail analyzed an email from Qt [interest] mailing list, found there a link
(parsed it), mis-interpretted it, rendered as a link, and considered the whole
email as a spam.

Link: https://bugreports.qt.io/issues/?jql=text%20~%20%22gadget%20qml%22

KMail's details on why it considered it as a scam:

> This email contains a link which reads as
> 'https://bugreports.qt.io/issues?jql=text ~ %22gadget qml'
> in the text, but actually points to
> 'https://bugreports.qt.io/issues?jql=text ~ %22gadget qml%22'.
> This is often the case in scam emails to mislead the recipient

Also, every time you click on a link, message view makes the scam "inline
message" visible again. Like, you close it via the (X) «Close message» button,
click on a link, and it re-appears again with an animation.

STEPS TO REPRODUCE
1. Get this email message
https://lists.qt-project.org/pipermail/interest/2022-January/037848.html, and
somehow open it via KMail

OBSERVED RESULT

Scam warning.

EXPECTED RESULT

No warnings.
