For months Kmail has worked with SASL. Beginning yesterday, however, after updating some packages, SASL is failing. Kmail gives me the following error. Sending failed: Authorization failed, An error occurred during authentication: SASL(-4): no mechanism available: No worthy mechs found authentication not supported At first I thought I had a problem with my provider, but Firefox, Thunderbird and other packages which use SASL appear to be working. I renamed my Kmail config files and re-started Kmail with no config. I added a POP and SMTP account and tried to send mail, that failed as well. I have re-installed all the cyrus-sasl packages, but that didn't fix the problem. I then tried an un-install and re-install of all the cyrus-sasl packages except the base cyrus-sasl package (removing it means removing a lot of other packages). SuSE 9.3, Kmail 1.8.1 (KDE 3.4.1), cyrus-sasl 2.1.20-7 Any ideas on how to fix this without having to completely re-install SuSE 9.3? Thanks.
