How to handle Gmail folder names in different languages?

Hey everyone, I’m working on a project that needs to access specific Gmail folders like the ‘All Mail’ and ‘Spam’ folders. But I’ve run into a problem. It looks like these folder names change based on the user’s language settings. For example, ‘All Mail’ shows up as ‘Todos’ for Spanish users.

I’m wondering if there’s a way to deal with this. Does anyone know if Gmail has standard names for these folders that don’t change with language? Or maybe there’s a trick to figure out which folder is which, no matter what it’s called?

If not, I guess I’ll need to make a list of all the possible names in different languages. But that seems like a lot of work. Any ideas or suggestions would be super helpful!

Here’s a quick example of what I’m trying to do:

def get_gmail_folder(folder_name):
    # This doesn't work for non-English users
    if folder_name == 'All Mail':
        return imap_connection.select('[Gmail]/All Mail')
    elif folder_name == 'Spam':
        return imap_connection.select('[Gmail]/Spam')
    # ... and so on

How can I make this work for users in any language? Thanks in advance for your help!

I’ve dealt with this issue before in a cross-cultural email management system. One effective approach is to use Gmail’s IMAP protocol’s X-GM-LABELS extension. This extension provides unique identifiers for system labels that remain consistent across languages. For instance, ‘^a’ corresponds to ‘All Mail’ and ‘^s’ to ‘Spam’, regardless of the user’s language settings.

Here’s a basic implementation:

def get_gmail_folder(folder_type):
    if folder_type == 'All Mail':
        return imap_connection.select('"[Gmail]/All Mail"', readonly=True)
    elif folder_type == 'Spam':
        return imap_connection.select('"[Gmail]/Spam"', readonly=True)

    # Search for messages with the corresponding X-GM-LABEL
    label_map = {'All Mail': '^a', 'Spam': '^s'}
    _, msgs = imap_connection.search(None, f'X-GM-LABELS {label_map[folder_type]}')
    
    return msgs

This method should work universally, eliminating the need for language-specific folder name mappings.

I encountered a similar challenge when building a multilingual email client. In my experience, a more reliable approach is to rely on IMAP’s special-use attributes rather than folder names, which change based on the user’s language settings. Gmail, for example, assigns language-independent attributes such as \All for the All Mail folder and \Junk for Spam. By fetching all mailboxes and checking for these attributes, you can determine the correct folder regardless of its localized name. Here is a Python example that illustrates this approach:

 def get_gmail_folder(folder_type):
     _, mailboxes = imap_connection.list()
     for mailbox in mailboxes:
         flags, delimiter, name = mailbox.decode().split(' ', 2)
         if folder_type == 'All Mail' and '\\All' in flags:
             return imap_connection.select(name.strip('"'))
         elif folder_type == 'Spam' and '\\Junk' in flags:
             return imap_connection.select(name.strip('"'))

     return None  # Folder not found

hey, i had this issue too. what worked for me was using the IMAP folder IDs instead of names. they’re consistent across languages. you can fetch the list of folders and their IDs, then use those IDs to access specific folders. it’s a bit more work upfront but saves headaches later. hope this helps!
