Steps to reproduce the error

I send a mail with an attachment of 3.5MB from another email account to account "foo". I'd expect offlineimap to ignore that message as the limit is 2MB, but it gets downloaded as usual.

Did I not configure it right?

Hello, I am interested in working on this issue and would like to be assigned to it. I have experience in Python and believe I would be a good fit for this task. Adding the maxsize under [Repository foo-Remote] and removing from the [Account foo], will help in this case. Please let me know if I can be assigned to work on this issue. Thank you!

@lokeshwarlakhi Would you also check to see if this issue possibly exist in , (the new python3 version), and if yes, also submit Pull Request there with a python3 version of your Pull Request from this version here?
