[MlMt] gmail folder's names

[Paula R. T. Coelho]

i use two gmail accounts with mailmate (and a real IMAP account).

i noticed one of the google accounts have folders names as "usual", say 
[Gmail]/Archive, [Gmail]/Trash etc, but the other account (several years 
older) have folders like [Google Mail]/Archive, [Google Mail]/Trash etc.

anyone knows why?
it doesn't bother me, but i'm curious how it came to be like this, 
[Gmail] vs [Google Mail] folder names...
