Item Codes
message/partial content type. MIME compliant mailers or user agents that receive
the fragments may automatically re-assemble the fragmented message. (MTA
channels must be marked with the defragment keyword in order for automatic
message re-assembly to occur.)
The size of a block may vary from site to site. Sites can change this value from its
default value of 1,024 bytes. Use the MTA SDK routine mtaBLOCK_SIZE to determine
the size in bytes of a block.
The item_length field specifies the maximum block size per message or message
fragment. By default, no limit is imposed.
MTA_FRAGMENT_LINES
Specify the maximum number of message lines per message. If, when the message
is enqueued, the number of message lines exceeds this limit, then the message will
be fragmented into smaller messages, each fragment with no more than the
specified number of lines. The individual fragments are MIME compliant messages
that use MIME’s message/partial content type. MIME compliant mailers or user
agents that receive the fragments may automatically re-assemble the fragmented
message. (MTA channels must be marked with the defragment keyword in order
for automatic message re-assembly to occur.)
The item_length field specifies the maximum number of message lines per
message or message fragment. By default, no limit is imposed.
MTA_FROM
Specify the address to use in the message header’s From: header line. The
item_address and item_length fields specify the address and length of a text string
containing the From: address. The length of the string may not exceed ALFA_SIZE
bytes. Only one From: address may be specified.
If this action is not used, then the From: header line will be derived from the
envelope From: address.
MTA_HDR_ADRS
Specify MTA_HDR_ADRS to request that the message also be sent to recipient addresses
found in any input header files. The item_address and item_length fields are
ignored for this item code.
