I have moved Thunderbird from the new Microsoft Outlook and I am very happy with Thunderbird except for one thing.When sending an email I often get the error message: "your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent-jemsym@aussiebb.com.au." How can I correct this? I have checked the outgoing SMTP details and have changed a couple of things with AussieBroadband. the problem remains. Can you help?
