--- Comment #8 from Axel Braun <[email protected]> --- In 5.8.2 I found that sending is completely blocked (you have to kill the kmail-process!) if the S/MIME certificate that is set in the identity is expired. Once the certificate is removed, everything works as expected. I guess this is causing the big timeouts when sending as well. Can you verify this? -- You are receiving this mail because: You are the assignee for the bug.
