Description Rolf Eike Beer 2019-08-21 16:37:49 UTC

I have received a mail with many recipient in To: as well as a "X-YMail-OSG:" header (from AOL). Both headers are long, but correctly folded.

When I now bounce that mail these lines get unfolded, breaking the 1000 char length limit of SMTP and are correctly rejected by my mail server.

KDE Frameworks Version: 5.45.0
Qt Version: 5.9.4

This could be related to bug 409169, I'm unsure if it hits the same code paths.
