SUMMARY

I'm using ArchLinux and I'm using version 21.04.2-1
The issue is that I'm using HTML border in signature.
I've tried to configure borders to have size=0 and I've configured it through the UI. Problem is that, after receiving the message at the other end(or even in the KMail Inbox) the borders have size bigger than 0.

STEPS TO REPRODUCE
1. Create signature with borders size = 0. Can be simple 2x2.
2. Fill the table with any data.
3. Send it to anyone

OBSERVED RESULT
Borders have different size then they should.
The border-size is greater than 0.
Tested on Office365, GMail. Same result is on GNOME Evolution.

EXPECTED RESULT
Borders size are 0 as set.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: ArchLinux Kernel 5.12.14-arch1-1
KDE Plasma Version: KDE Plasma 5.22.3-1
KDE Frameworks Version: 5.83.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
None

Hello,

I can confirm the above bug still is present in KMail 5.22.3 on KDE Plasma 5.27.3, running on openSUSE Tumbleweed 20230403.

When I 'copy-paste' standard HTML email signature content into an idientity's Signature settings panel, the signature looks as expected, but borders are applied to it when using it within an email.

The HTML email signature file is architected accordingly to email signature development best practices and standards, and works as expected in desktop email clients like Evolution, Outlook Desktop, Thunderbird etc., or online email clients like Gmail, Outlook Web App etc., with little rendering variations.

KWallet shouldn't add borders to HTML email signatures, and should render signaures in a more standardized way (similarily to other email clients). 

Best,
Márton Lente

I have been having the issue for a long time.
I currently have KMail Version 5.23.2 (23.04.2) on ArchLinux, KDE Frameworks Version 5.106.0, Qt Version 5.15.9 (built against 5.15.9).

It seems that Kmail totally modify the inline style of the signature instead of letting it untouched.
