32-bit archs can only do up to 2 gig quotas. If you're not on a 64-bit
platform, you'll have to either knock that back some or remove it
entirely.

When local delivery fails a certain number of times, Courier will start
sending "456 Temporary failure" in respons to any more incoming mail for
that user, this prevents an overquota account from filling up the spool
also. Fix the quota issue with local delivery and then run:

/path/to/courier clear username@domain.com

delivery should start working for that user again, without the courier
clear, it would normally take an hour or two for Courier to realize local
delivery was working and begin accepting external mail for the user again.
