If I understand you correctly, you're saying that LDA parses X-Original-To 
even without having the lda_original_recipient_header variable set.  If 
that's the case, I'd think that setting "lda_original_recipient_header = 
X-Original-To" would be a NOOP as far as LDA is concerned, and you 
could transition to LMTP at your leisure.
