I have 2 identity in kmail, each of those have one email account associated. For each account I have, when I send an email, I see that only the default smtp is used, instead of the default smtp associated to the account I don't remember such behavior with the previous kmail version. The result is that the email are marked as spam.
I found the problem. The default outgoing account was deleted from each identity. I set them back, so personally I have resolved the issue, but maybe the bug exists.
