Debugging Mail Flow Using Test Messages: Trace
Masquerading If you specified that the Envelope Sender of a message should be
transformed, the change is noted here. You enable masquerading for
the Envelope Sender on private listeners using the
listenerconfig ->
edit -> masquerade -> config
subcommands.
For more information, see Configuring Routing and Delivery
Features.
Envelope Recipient Processing
These sections summarize how the appliance affects the Envelope Recipients you supply. (That is, how
the RCPT TO command would be interpreted by the configuration of the appliance.) The
trace
command prints “
Processing Recipient List:” before this section.
Default Domain If you specified that a listener to change the default sender domain of
messages it receives, any changes to the Envelope Recipients are
printed in this section.
For more information, see Configuring the Gateway to Receive Email.
Domain Map Translation The domain map feature transforms the recipient address to an
alternate address. If you specified any domain map changes and a
recipient address you specified matches, the transformation is printed
in this section.
For more information, see Configuring Routing and Delivery
Features.
Recipient Access Table (RAT) Each Envelope Recipient that matches an entry in the RAT is printed
in this section, in addition to the policy and parameters. (For example,
if a recipient was specified to bypass limits in the listener’s RAT.)
For more information on specifying recipients you accept, see
Configuring the Gateway to Receive Email.
Alias Table Each Envelope Recipient that matches an entry in the alias tables
configured on the appliance (and the subsequent transformation to one
or more recipient addresses) is printed in this section.
For more information, see Configuring Routing and Delivery
Features.
Pre-Queue Message Operations
These sections summarize how the appliance affects each message after the message contents have
been received, but before the messages are enqueued on the work queue. This processing occurs before
the final
250 ok command is returned to the remote MTA.
The
trace command prints “Message Processing:” before this section.
