Each person using email is assigned a maximum quota limit for his or her email account? This limit applies whether you are using Webmail, Thunderbird, Outlook or another email system and is often more relevant to those using IMAP rather than POP3. The typical quota allocation for each mailbox is 250 megabytes (MB).
What happens when I exceed my quota limit?
Once you have exceeded your quota, you enter a 28 day grace period. During the grace period, you will still be able to receive email but will receive weekly warning notices. These notices show how far over quota you are and how long you have to correct this situation.
If you are still over quota when the grace period expires, you will no longer be able to receive new email. Any email for your account will be returned as "undelivered mail" with the message 'error writing message: Disk quota exceeded'. You will still be able to access your email and send mail to others, however incoming email will stop until you free up some space for the new messages.
Staying within the Quota Limit
You can avoid exceeding your quota by following the guidelines listed below. Most of these guidelines apply to those using IMAP or Webmail but should be considered by those doing POP3 also.
