Whenever I try to send an e mail or reply to an email I get an error message telling me that the Connection to the Outgoing Server SMTP was lost in the middle of the transaction. I have check with my ISP (Telstra Australia) and there is no fault at their end. The account settings in Thunderbird are correct and I have the latest version. I can receive e mails but cant send any. This problem has only occured in the last couple of days. Can you help please.
