Subject: Your mailbox is almost full
Dear mail user,
Your e-mail $MAILBOX@$DIR is about to reach its maximum quota. You are using $MBOXSPACE MB ($MBOXPERCENT%) out of the maximum quota $HARDQUOTA MB.
We would kindly suggest you to delete some older messages and purge them to free some space in the mailbox. If the quota limit is reached, you won't be able to receive any new messages and the sender will receive 'mail quota exceeded' notifications.
Another option is to configure your POP3 mail client (e.g. Microsoft Outlook, Mozilla Thunderbird or Apple Mail) to delete the messages on the server mailbox every time the mail account is read.
This is an automated message, do not reply. If you require any assistance, please open a support ticket at http://*******/support.php .
