periodically, a warning mail, indicating the mailbox is almost full with the
percentage full, is also delivered to the recipient mailbox.
Only one warning, either in response to an IMAP Append or Copy command
warning or in response to an SMTP mail, will be generated within a configurable
time period (WARN_MAIL_SEND_INTERVAL system parameter).
It is possible to set the limits at each level to indicate no limit.
Again the mailbox size used for checking is the total of the size of all mailboxes
below a root mailbox.
11.2.3 Max Mailbox Messages
The maximum number of messages that can be in all mailboxes below a root
mailbox is configurable at the following levels which are listed in order of usage,
i.e. if the Mailbox Root level value is specified then it is used, otherwise the
Service Package level value is used, and so on:-
• Mailbox Root
• Service Package
• System
Within an IMAP session, if an Append or Copy command causes the maximum
number of mailbox messages to be exceeded, then the mail will not be
delivered to the targeted mailbox and a NO response will be returned indicating
to the user that the max mailbox message number limit has been exceeded.
If a mail arrives via an SMTP session, which causes the maximum number of
messages for the mailbox hierarchy to be exceeded, then the mail will not be
delivered to the recipient, but instead an NDR “Mailbox Full” mail is returned to
the sender. Also, periodically, mail received by such a mailbox will cause a
warning mail to be delivered to the recipient mailbox indicating the mailbox is
full. The minimum interval between warnings generated in this way is equal to
a configurable time interval (WARN_MAIL_SEND_INTERVAL system
parameter).
It is possible to set the limits at each level to indicate no limit.
The total number of mailbox messages for checking against the max mailbox
messages limit is calculated as the total number of messages in each of the
mailboxes below the root mailbox.
11.2.4 Max Message Retention Period
A maximum Message Retention Period is configurable at the following levels
which are listed in order of usage, i.e. if the Mailbox Root level value is specified
then it is used, otherwise the Service Package level value is used, and so on:-
• Mailbox Root
• Service Package
• System
