Depends on the environment; in many cases, the admin could, or may even
be expected to, raise the quota.

Also, you're assuming that users will be able to interpret an error
message, even a clear one, correctly, and that the MUA will always
convey the error to the user. I am not sure either of these assumptions
are always true. Logging is important so when the user calls in with "I
can't do X", the admin can see why quickly.
