I wonder if this patch causes your lmtp/lda processes to start
assert-crashing (which at least with lmtp causes MTA to retry, with lda
might reject mail depending on config):

Since the bug appears to be in the mail delivery part, it would be much
easier to debug&fix it by looking at what goes wrong there.
