56<ul>
57<li>bodyp points to a sequence of bytes.
58It is <em>not</em> a C string (a sequence of characters that is terminated by '\0').
59Therefore, do not use the usual C string functions like strlen() on this byte block.
60Moreover, the byte sequence may contain '\0' characters inside the block.
61Hence even if a trailing '\0' is added, C string functions may still fail
62to work as expected.
63<li>Since message bodies can be very large, defining xxfi_body can
64significantly impact filter performance.
65<li>End-of-lines are represented as received from SMTP (normally CR/LF).
66<li>Later filters will see body changes made by earlier ones.
67<li>Message bodies may be sent in multiple chunks, with one call to 
68    xxfi_body per chunk.
