Hi All, This is not a Linux Kernel related query but is rather on the infrastructure to manage patches using git. Before asking here, I did some search on Internet and also posted this query in a different Linux forum but no luck so far. Hence thought of asking here as someone might have faced this issue, while using the git send-email feature. I've installed git-core and git-send-email packages on my Ubuntu machine and I'm using git to generate patch. Now I want to send this patch, but while doing so, git returns with following error: "5.7.0 Must issue a STARTTLS command first." Some information regarding my setup: slackjaw@swamp:~/linux-next$ cat /etc/issue Ubuntu 11.10 \n \l slackjaw@swamp:~/linux-next$ cat ~/.gitconfig [user] name = Amit email = <XYZ@xyz.com> [sendemail] smtpserver = smtp.googlemail.com git command to send patch: slackjaw@swamp:~/linux-next$ git send-email --to "abc@xyz.com" 0001-Adding-debugging-level-for-printk.patch The above command returns with error message as mentioned above, whereas my expectation was that git should ask me to enter my password and then send the mail to the destination mail id. I'm able to send and receive mails when I use thunderbird's default settings (In-fact I 'm sending this mail through Thunderbird) which means that there is no issue with the port number or the authentication method for the outgoing mails. -Amit
