Hello -- I have just upgraded from KDE 3.3 to 3.4.0. Now when I try to send an e-mail via KMail I get the following error: Sending failed: Authorization failed, An error occured during authentication: SASL(-4): no mechanism available: No worthy mechs found authentication not supported The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder. The following transport protocol was used: <Identity> I can still check for messages on the POP3 server that uses the same username and password as the SMTP server. Server name has not changed. What is the problem? Can someone help me? Mike ___________________________________________________ . Account management: https://mail.kde.org/mailman/listinfo/kde. Archives: http://lists.kde.org/.
