fetchmail -- unknown user generating two emails

fetchmail version: 6.3.6
sendmail version: 8.13.8
linux distro: centos 5

Hello,
I've just started using the above fetchmail/sendmail combo, but was
previously using versions of each that were several years old.

I'm using one multidrop box which has always worked well, as the
server I'm imapping from uses qmail.

Fetchmail is working just fine, except email from the outside world
addressed to an unknown user generates *two* emails, both to
postmaster@xxx.com: 1) the normal unchanged email and 2) a "Mail
delivery failed: returning message to sender" from "MAILER-
DAEMON@xxx.com.

Also, there are no X-Fetchmail heades added.

The older version of fetchmail did include the X-Fetchmail warnings
and only generated one normal unchanged email to postmaster. I'd like
the current version to behave this way, as I pipe mail addressed to
postmaster into an application that separates the emails into spam,
old_users, maybe_legitimate, etc.

I'm running fetchmail as root (yes, I know I shouldn't). The
fetchmailrc includes:
set no bouncemail (wasn't needed in older version)
localdomains xxx.com
using imap (as opposed to pop3)

I've tried every combination of settings I can possibly think of in
fetchmail and sendmail (which are to convoluted to discuss, unless
specifically asked).

Viewing log files generated by the fetchmail -v -v options indicate to
me that fetchmail is doing this (as opposed to sendmail), but I just
don't know. Perhaps the newer fetchmail is supposed to behave this
way?

If anyone could help me on this, I'd sure appreciate it... I'm about
googled out on this one.

Thank you,

Future versions of fetchmail will refuse to run as root.

I'd suggest you try the fetchmail-users mailing list (having first
upgraded to fetchmail 6.3.8), including the output of "fetchmail
-nosyslog --nodetach -vvv" (as detailed in the fetchmail FAQ) and the
contents of your .fetchmailrc file.

Thanks Rob, I somehow overlooked the fact that there is a fetchmail
users site.
