Can't create mailbox in server

My email server has a mailbox called Sent Messages. eM Client tries to create a new one, named “Enviados” - it’s the same “sent messages” but in portuguese.

This generates a error and eM Client thinks that it is offline and no longer reads the messages from that point.

Turn a mess.

I have used IMAP protocol, because it’s important to me keep sent messages in the server. How can I go out from this crash?

Is it possible record sent messages in server with POP protocol?

One sugestion: let user change the name of the count’s folders would solve the problem?
