qmail delivery problem

[Aasef Iqbal]

Hi! 

I recent found a problem with our virtually hosted domains on a Redhat
box, with qmail and PLESK.  When I send a mail to user BOB at Host1.com
it appears on BOB at Host2.com as well.  I logged in to BOB at Host2.com and
could actually draw emails from BOB at HOST1.com.

I tried to send email to BOB at HOST1.com and the log files showed the
something as following

Feb 14 14:32:12 pl qmail: 1108413132.829153 new msg 721316
Feb 14 14:32:12 pl qmail: 1108413132.829266 info msg 721316: bytes
1406 from <aneedz at gmail.com> qp 29227 uid 2020
Feb 14 14:32:12 pl qmail: 1108413132.837313 starting delivery 100: msg
721316 to local 2-bob at host1.com
Feb 14 14:32:12 pl qmail: 1108413132.837416 status: local 1/10 remote 1/40
Feb 14 14:32:12 pl qmail: 1108413132.850939 delivery 100: success: did_1+0+1/

Now this email actually appears in BOB at Host2.com when I login to
(hord) webmail or access it using pop server.

What may be wrong and the remedy ....

please comment...
