 The sender comes from the same domain,same time, same sender and everything. Thats i suspected some problem. Even from trusted senders and spammers. Im still checking for other clients having the same problem.

I don't think we have to go back to the logs, just use some
logic(:-)... We see two separate (by 20 minutes!) messages, possibly
containing the exact same message, being handled by smtpd/the header
checks... and then passed on to the hold queue. This is a very strong
indicator that it isn't your system that is having the problem
(although it has to handle the effects of the error), since this, in
all likelihood, couldn't happen unless those messages were handled in
two separate SMTP-conversations.

If you do happen to look at the logs, take just one of teh messages,
the first one, and look through the whole chain... is there _any_
errors indicated? Like a dropped connection? If you have logs split,
remember to look in the error and warning file too.

Are all the duplicates from the same sender/sending domain? If so,
call them... and inform them (in a nice manner:-) that they have a
problem to solve.
If not... Well, we'll get to that eventually:-).
