Three programs are used to generate and administer quarantine digests. They are:
pmx-qdigest, pmx-qdigest-approve and
pmx-qdigest-expire. These programs are run automatically as scheduled jobs.
See "Scheduling Digest Tasks" for the recommended settings for the scheduled jobs.
These scheduled jobs are used to automatically perform the following tasks:
- Generate Digests: The pmx-qdigest program analyzes quarantined
messages and generates quarantine digests. It functions according to the configuration in the
pmx-qdigest.conf configuration file; pmx-qdigest.conf
settings can be manually edited, or administered on the Digest Rules page
on the Quarantine tab in the PureMessage Manager. pmx-qdigest generates an
email for each configured user that lists all the messages in the quarantine that were intended
for that user.
- End User Release Requests: When users receive digests, they can release messages from
the quarantine by replying to the digest. To release a specific message from the quarantine,
users must click on the message's ID, which generates a reply email containing the message ID.
To release all messages listed in the digest, users must reply to the digest message.
- Process End User Release Requests: The pmx-qdigest-approve program
responds to release requests from end users. When an end user requests delivery of a message in
the quarantine, pmx-qdigest-approve releases the message and queues it for
delivery.
- Expire Pending Digests: PureMessage stores a
record of each quarantine digest. When an end user requests the release of a message,
pmx-qdigest-approve validates the release request against the archived
digest records. Periodically, (by default, every 5 days) the digest archive should be cleared.
The pmx-qdigest-expire program clears archived digest records.
Note: Some email clients (such as Microsoft Outlook) have built-in message filtering
that can be optionally enabled by the end user. These filters can result in quarantine digests
being filtered by the end user's email client. Users can either disable their local mail client
filter, or can adjust the filter to exclude PureMessage
quarantine digests. See "Exempting Digests from Local Filters" for instructions on the
latter.
