Oh, that's annoying. Dovecot LDA doesn't actually add this header, it was your MTA that added it. But looks like I hadn't checked what the MTAs actually write to the header when I added this feature to LMTP, and nobody had mentioned this before either. I wonder if anybody's system breaks if I just change it now..
