I would think problem would be a known one, but perhaps not? In this
environment, we use a .mc file of roughly (this debugging output is
from 8.6.12, but the problem still exists under 8.7.3).
MASQUERADE_AS(mit.edu)
FEATURE(allmasquerade)
LOCAL_USER(root)
define(`LOCAL_RELAY', `mit.edu')dnl
define(`MAIL_HUB', `mit.edu')dnl
MAILER(local)dnl
MAILER(smtp)dnl
If mail on such a client is sent to both a full-quallified address and
a non-fully qualified address, one is resolved to the relay mailer and
the other to the smtp mailer, and so the message is twice-delivered.
For instance:
sendmail -odi -v -d0.1,20,25,26,29.5 jhawk@mit.edu jhawk
yields two deliveries to the MXes of mit.edu; debugging on the
recipient addresses is:

I'm afraid I'm not knowledgable enough on how the choice of mailers is
made in order to determine where in the code the problem lies (how/why
does maplocaluser() pick a mailer), or what the solution is...
Thanks.
