Bug ID: 494945
Summary: "From" name with special character breaks email
sending

bad email
SUMMARY
kmail 6.2.1 from KDE Gear 24.08.1 fails to send E-Mails with two of my mail
providers (gmx.at and gmail). The server refuses to send the emails because
supposedly the "from" address is not mine.
I have isolated the issue down to the "ö" character in my name. If the from
address is "Stefan Dösinger <stefandoesin...@gmx.at>", sending fails. If I set
the name in the kmail identity to "Stefan Doesinger" or leave it empty, sending
succeeds.
This happens on a new KDE installation. Interestingly it does not happen on a
second system that has been upgraded over the years and the E-Mail setup is a
few years old. As far as I can see the difference in the generated emails is
this:
Bad version:
From: Stefan Dösinger <stefandoesin...@gmx.at>
Good version:
From: Stefan =?UTF-8?B?RMO2c2luZ2Vy?= <stefandoesin...@gmx.at>
Both versions also have these headers:
MIME-Version: 1.0
Content-Transfer-Encoding: base64
Content-Type: text/plain; charset="utf-8"
I have attached two email files for reference
STEPS TO REPRODUCE
1. Start with a fresh KDE setup, e.g. create a new Linux user
2. Set up an E-Mail account with a special character in the sender name (not
the sender address)
3. Try to send an email
OBSERVED RESULT
Sending the Email is rejected. It depends a bit on the exact provider. gmx says
"transaction failed" when sending. gmail seemingly sends, but the recipient (in
this case my gmx address) rejects the email because supposedly the From address
is invalid.
EXPECTED RESULT
Email gets sent correctly
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Gentoo, KDE 24.08.1
ADDITIONAL INFORMATION
The "good" system is an x86_64 system, the bad one an aarch64 one. But I
suspect the platform doesn't matter. Instead, something in ancient config files
hides the bug on one of them
