Hi, I have had a problem for quite a while with KMail where sometimes messages do not send properly. The error message that appears when this happens isn't particularly helpful, it just says: The server responded: "" I have access to the logs of the mailserver that is being used, and I can see that sometimes, even though the messages don't look like they have been sent, I can see entries in the maillog of the messages going. KMail seems to think that they haven't gone though, and they stay in the outbox. However, sometimes I get the message, and when I check the maillog, the message HAS NOT gone. I cannot seem to find any pattern emerging with this behaviour. Has anyone else ever experienced this? I haven't been able to find any other references to this problem where the server responds with a blank error message. Thanks, Tim
