Postings from one of our lists comes with the actual recipient in the bc
line along with the normal [log in to unmask] in the to line. Since I
don't see a bc in the header, I think this is the handiwork of our
Groupwise mua, although this doesn't happen with all of our lists (only
this one I've noticed so far)  If so, any ideas on what's causing this?
Here's the relevant headers, slightly sanitized:
