If you are a linux user just take a look at the processes and load on
server by using the command "top" during the known peak hours of
operating. Look for spawned processes using lots of cpu.

If the server isn't receiving them twice, then I'd look at the
possibility of them being pop'd twice somehow. I don't know how that
might happen (all of my Outlook clients are using IMAP). I presume
your customers are using pop3.

I checked smtp logs for these mails.
But I couldn't see any duplicated mail.
What else may the problem be ?

I use vpopmail on qmail.
I have many customer domains on that mail server.
One of these customer domains tells me that, they rarely receive
the same mail a few times. That problem becomes nearly once a week
for this customer.
I haven't any complain from my other customers.
They use outlook or o.express for their mails.
What may the problem be ?
Do I have to change my configuration ?
This can be caused by the load on your server. Sometimes a long scan
time will cause the sending server to time out before the scan is
complete and your server acknowledges receipt. The sending server
then obligingly resends. Check the smtp logs for the corresponding
duplicate email. You'll see 2 receipts for it if this is what's
happening.
