CloudPull Throttling

In order to keep Google's IMAP servers running smoothly for all of their customers, Google has IMAP usage limitations. Google enforces IMAP usage limitations by throttling back the speed at which it responds to IMAP clients and by temporarily disabling IMAP access after excessive usage. In order to work within Google's usage limitations, CloudPull limits the number of messages it downloads during each backup cycle. CloudPull downloads 5,000 messages per backup cycle per account, and uses up to four simultaneous connections per account for downloading messages.
