I GIVE UP !!!

This process of downloading emails through the IMAP protocol is not working flawlessly with large amount of emails from my experience. I tried several clients with my mere 3GB account and it took AGES (And didn't finished). It seems a job that the client won't pay for all the time that will be spent on doing it, And I can't even promise it will succeed.....
Something you got to know your limitations......Maybe I'll just offer him to arrange his web gmail folder for deletion or something like that to cover some of the effort i've put into this all thing
