Note - This section applies to the Sun Internet Mail Server - Enterprise Edition only. It further applies to the UNIX to UNIX Copy Program (UUCP) channel, Sun Message Store channel, /var/mail channel, and pipe channel only.
Occasionally a large message must traverse email systems that impose message size limitations. MIME allows the breaking up of a large message into smaller messages, a process known as fragmentation. A Message/Partial Content-Type header field that appears in each of the smaller messages or fragments contains information that helps reassemble the fragments into one message, a process known as defragmentation.
By default, the Sun Message Store channel, /var/mail channel, and pipe channel do not defragment a message. You can configure each of these channels to reassemble a fragmented message upon receipt.
For complete information on message fragmentation and defragmentation, and the Message/Partial Content-Type header field, refer to RFC 1521.
