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