< LI > Since the message body may be very large, setting SMFIF_CHGBODY may significantly affect filter performance.
< LI > If a filter sets SMFIF_CHGBODY but does not call smfi_replacebody, the original body remains unchanged.
< LI > For smfi_replacebody, filter order is important. < B > Later filters will see the new body contents created by earlier ones.< / B >
