Normally, I use imaplib (python lib.) to display mailbox name (example [Gmail]/Spam ) But recently I found my friend account has a different prefix (example [Google]/Spam).
What's the difference between normal account and my friend's account.:)
My guess is that in some territories, e.g. UK, the name 'Gmail' was trademarked and so 'Googlemail' was used instead. Perhaps this accounts for the different mailbox names. Recently this dispute was resolved though, and 'Gmail' is available in the UK again.
