Yes, I have the same problem and I complained about it 2 years ago
to no avail. The TO command prefix isn't exactly "undocumented"; it
appears in the release notes around 1.6b-1.6c, as I recall. Over a
year ago, I asked on this list if anyone was using the TO command,
and the only response I got was to the effect that "there is no TO
command." The specific problem with bounced mail from the unknown
users [log in to unmask] and [log in to unmask] comes from the confirmation
letter sent to users who ask to subscribe to a list which is
"Subscription= Open,Confirm", so I would guess that any postmaster
who has lists like this gets some bounces. I get about 10 of these
a week.
 
I would certainly like to see the TO command prefix removed.
