One of the beauties of qmail is that it does what you tell it to do:
no more, no less. If you send a message to three recipients that share
a mailbox, of course qmail will deliver three copies that differ only
in the Delivered-To header field.
If you want to accept only one copy, you can put a duplicate filter on
the mailbox, e.g. using Russ Nelson's eliminate-dups script
(http://www.qmail.org/eliminate-dups) or a procmail recipe like:
# Use a 10Kb cache of Message IDs received to avoid duplicate messages
:0 Whc: .msgid.lock
| formail -D 10240 .msgid.cache
# Save probable duplicates for inspection
:0 a:
spool/dupes
