The
XPRT
command replaces the SMTP
DATA
command. The command accepts the
transfer of the message part after the command is issued. The command is
completed with a single period on a line followed by a return (which is the same

The special keyword
LAST

Notes on Defining Variables
•
When you define variables with the
XDFN
command, note that the actual
command line cannot exceed the physical limit of the system. In the case of
the IronPort C300D appliance, this limit is 4 kilobytes per line. Other host
systems may have lower thresholds. Use caution when defining multiple
variables on very large lines.

•
You can escape special characters using the forward slash “
/
” character when
defining variables key-value pairs. This is useful if your message body
contains HTML character entities that might be mistakenly replaced with
variable definitions. (For example, the character entity
contains HTML character entities that might be mistakenly replaced with
variable definitions. (For example, the character entity
™
defines the
HTML character entity for a trademark character. If you created the command
XDFN trade=foo
and then created a IPMM message containing the HTML
character entity “
™
” the assembled message would contain the variable
substitution (“
foo
”) instead of the trademark character. The same concept is
true for the ampersand character “&” which is sometimes used in URLs
containing GET commands.
