Everything happens normally for the forwarded messages and for my POP3 account. Expected results: It's not a big deal, but the status and the arrow are very useful.
Can we get an imap log to see what's going on between Thunderbird and your imap server ? (https://wiki.mozilla.org/MailNews:Logging)

per bug 667950 comment 2 "we require that the server support the built-in flags that the IMAP RFC mandates (which includes \answered, but not forwarded, I don't think)" I don't see answered flag in protocol log, do you?
