Version: (using KDE KDE 3.0.8) Installed from: Unlisted Binary Package OS: Linux This will probably happen only once/user. After installing kde from scratch, my Defalu identity did not have an e-mail address. I composed a message, and when I tried to send I got the "Please set the email address of the default identity. Kmail does not work without it" I clicked ok, and added an e-mail address to the default identity using the settings dialog. (The compose window was still open) Then I clicked "send" and all went well, except that my SMTP host gave an error that the From field had an empty e-mail address, which it did. The message in the outbox did not have an e-mail address in the From field. It is very easy to reproduce this behaviour: just delete the e-mail address from the default identity, and then compose a message and try to send it. In order to correct the identity in the message that was now in the outbox, I had to define another identity. The compose dialog then enabled me to chose my identity, and correctly copied the e-mail address for the dafault one.
This bug is also present in KDE 3.1 RC2 (compiled with Gentoo packages).
that sounds like a composer problem
This problem has finally been fixed.
