Debugging Mail Flow Using Test Messages: Trace
Work Queue Operations
The following group of functions are performed on messages in the work queue. This occurs after the
message has been accepted from the client, but before the message is enqueued for delivery on a
destination queue. “Messages in Work Queue” is reported by the
status and status detail
commands.
Masquerading If you specified that the To:, From:, and CC: headers of messages
should be masked (either from a static table entered from a listener or
via an LDAP query), the change is noted here. You enable
masquerading for the message headers on private listeners using the
listenerconfig -> edit -> masquerade -> config subcommands.
For more information, see Configuring Routing and Delivery
Features.
LDAP Routing If LDAP queries have been enabled on a listener, the results of LDAP
acceptance, re-routing, masquerading, and group queries are printed
in this section.
For more information, see LDAP Queries.
Message Filters Processing All messages filters that are enabled on the system are evaluated by the
test message at this point. For each filter, the rule is evaluated, and if
the end result is “true,” each of the actions in that filter are then
performed in sequence. A filter may contain other filters as an action,
and the nesting of filters is unlimited. If a rule evaluates to “false” and
a list of actions is associated with an
else clause, those actions are
evaluated instead. The results of the message filters, processed in
order, are printed in this section.
See Using Message Filters to Enforce Email Policies.
Mail Policy Processing
The mail policy processing section displays the Anti-Spam, Anti-Virus, Outbreak Filters feature, and
disclaimer stamping for all recipients you supplied. If multiple recipients match multiple policies in
Email Security Manager, the following sections will be repeated for each matching policy. The string:
“Message Going to” will define which recipients matched which policies.
