When I install the package from Fedora 12 it fails with the following message: "Sending of message failed: Please verify that the Mail and Newsgroups Accounts settings are correct and try again." There appears to be no difference between the two particularly as they are using the same user preferences. It seems to me that there must be something different between the two: Following are the two installations I have installed: thunderbird-3.0-3.13.rc2.fc12.i686 thunderbird-3.0rc2.tar </body> </html>
