Email client not talking proper IMAP? Unfriendly to other clients
There are standards for this, as in the XLIST command for IMAP, which has recently been superseded by the Special-Use extension of the IMAP LIST command. Gmail supports these, and Fastmail, and mail clients like Thunderbird and Opera, and even Outlook 2013 apparently. The problem with the Android Mail app (at least for me) is that it doesn't understand these commands, and simply creates folders with localized names. In Opera Mail and also in Thunderbird, you can also manually pick the IMAP folders to use for storing deleted and sent messages. So you could choose the IMAP folders that the Android client is already using, don't forget to make these changes to all the mail clients if you have multiple machines accessing that IMAP account. That might help.
