Unable to Create Deeply Nested Folders With Gmail

If you have problems creating new folders for your IMAP Gmail (or Google Apps) account, please be aware that Gmail has a limit on the number of characters for a Label, and in Postbox, folder names are converted into Labels on the server. 

So a folder in Postbox such as:

INBOX / Clients / Active / ClientName / AgencyName 

gets translated into Gmail as a Label 

INBOX/Clients/Active/ClientName/AgencyName

and if that Label string is too large, Gmail (or Google Apps) will reject it.
