When I use my @qq.com email account to send emails via Thunderbird, I find that after showing that the message has been delivered successfully, it just show it is now copying the message into the sent box. Then it gets stuck and won't advance. However, after checking my sent box, I found that the email is actually successfully sent and stored.
