E-mail Storage Quota

Quota Warnings

Quota warning messages are sent to the ARES/RACES user when each warning threshold is exceeded. The warning messages for each threshold are sent to the user's ARES/RACES mailbox and to the user's external e-mail address. Warnings sent to external e-mail addresss include the ARES/RACES e-mail address so the user can tell which mailbox is becoming full.

Quota warnings for each threshold are sent only once; there is no reminder. When a warning is received, the user should take immediate steps to clear out the mailbox and keep it clear, or else risk having incoming mail rejected.

Example 75% threshold warning sent to an ARES/RACES e-mail account:

From: postmaster@<domain>
Subject: Quota Warning

Warning: Your mailbox is over 75% full.

Example 90% threshold warning sent to an external e-mail address:

From: postmaster@<domain>
Subject: Quota Warning

Warning: Your SCCo ARES/RACES mailbox <callsign>@<domain> is over 90% full.

Non-Delivery Notification:  mailbox is full

When a mailbox is full, additional incoming messages will be refused. People who try to send a message to a mailbox that is full will receive a Delivery Status Notification (DSN, also commonly called a "bounce message") from their sending e-mail system indicating that the message was rejected by the recipient's server. The exact format of the DSN may vary somewhat. But it usually looks something like the following:

From: MAILER-DAEMON (Mail Delivery System)                    
Subject: Undelivered Mail Returned to Sender

This is the mail system at host <sender's mail system hostname>.
