Version: 1.12.0 (using KDE 4.3.0) OS: Linux Installed from: Ubuntu Packages Since upgrading from KDE 4.2.4 to KDE 4.3.0 KMail no longer uses a correct signature separator ("-- ", <dash><dash><space>) to separate the signature from the message body, but instead only uses two dashes. The signature separator is still correct when composing the mail, but after sending the message it shows up with incorrectly truncated whitespace for the separator line, which is also what reaches the recipient.
Fixed with r1012151. Actually, KMail sent those mail correctly, it is just that KMail drops the space when displaying, you can verify that by viewing the source of the mail.
Thanks for the speedy solution! I can confirm that this is a pure display issue and mails are sent correctly. May I still ask for a downport to the 4.3 branch?
