Debugging Mail Flow Using Test Messages: Trace
The Trace page (and trace CLI command) prompts you for the input parameters listed in Table 40-1.
Table 40-1 Input for the Trace page
Value Description Example
Source IP address Type the IP address of the remote client to mimic the
source of the remote domain. This can be an Internet
Protocol version 4 (IPv4) or version 6 (IPv6) address.
Note: The
trace command prompts for an IP address
and a fully-qualified domain name. It does not attempt
to reverse the IP address to see if it matches the
fully-qualified domain name. The
trace command
does not allow the fully-qualified domain name field to
be blank, so it is impossible to test a scenario where the
DNS does not reverse match properly.

Domain Name of
the Source IP

mimic. If left null, a reverse DNS lookup will be
performed on the source IP address.

Reputation Score
(SBRS scores)
Type the SBRS score you want to provide for the
spoofed domain, or allow the system to look up the
SBRS score associated with the source IP address.
This can be helpful when testing policies that use
SBRS scores. Note that manually entered SBRS scores
are not passed to the Context Adaptive Scanning
Engine (CASE). See Editing Sender Reputation
Filtering Score Thresholds for a Listener, page 6-5 for
more information.

Message Body Type the message body for the test message, including
headers. Type a period on a separate line to end
entering the message body. Note that “headers” are
considered part of a message body (separated by a
blank line), and omitting headers, or including poorly
formatted ones can cause unexpected trace results.
