Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

When a client injects IPMM messages to the listener, it uses extended SMTP with the following key 
commands.

Syntax: 

This command replaces the SMTP 

MAIL FROM:

 command and indicates that what follows is an IPMM 

message. An IPMM job is initiated with the 

XMRG FROM:

 command. 

Syntax:

 

 

KEY=VALUE

The 

XDFN

 command sets the per-recipient metadata. Note that key-value pairs can optionally be enclosed 

in angle brackets or square brackets. 

*PARTS

 is a special reserved variable that indicates the index number as defined by the 

XPRT

 command 

(described below). The 

*PARTS

 variable is split as a comma-delimited list of integers. The integers match 

the body parts to be sent as defined by the 

XPRT

 commands. The other reserved variables are: 

*FROM

, 

*TO

, 

and 

*DATE

. 

Syntax:

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 way an SMTP 

DATA

 command is completed).

The special keyword 

 indicates the end of the mail merge job and must be used to specify the final 

part that will be injected.

After the 

LAST

 keyword is used, the message is queued, and delivery begins.

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 D-Mode-enabled 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.
