Your E-Mail Quota
Many accounts have a disk quota -- how much disk
space you can use to store your files (including email folders)
in your account. If you use more than this space, you are said
to have "gone over" or "exceeded" your quota.
If that happens, various
things may not work correctly, or you may not see new mail
messages until you return to within your quota allocation.
It is important to monitor your quota and make sure you do
not exceed it for proper functioning of your account and
protection of your files.
