Hi Folks, I set up Ubuntu 10.04 LTS on an EC2 Server Instance. I can't send mail from Thunderbird, it's retrieves it, just can't send any. I was successful otherwise, the squirrelmail web client works fine, so debugging is focused on how to get in authenticated. I followed the ISPConfig 3 on Lucid tutorial. Any ideas would be appreciated, -Jon
Please check the Thiunderbird account settings to ensure that smtp authentication is enabled for sending emails and that it uses the email addressa s username and the same password that you use for pop3/imap access.
