At line 1815 I see this call: char *new_header=rw_rewrite_header(mf->module, header.c_str(), RW_HEADER|RW_SUBMIT, addresst, &errmsg); That's a couple of spans above the checks for NOADDMSGID and NOADDATE. I set the former but not the latter. I attach a small test file to confirm what takes place. > If there's any intermediate step in your mail path, such as maildrop > or .courier forwarding the message somewhere, that can come across as > a locally-submitted mail, that's subject to header rewriting.

Some does... After looking a bit closer at the code, I think I could try a patch, next week, say. How about NOADDRTRANSCRIBE?
Try it; not sure about the name, NOADDRREWRITE sounds better.
