Qmail queue strange delivery problem

[RubM]

Hello everybody,

At the moment I have a really strange problem which I can’t tackle.

A colleague of my received a mail from a supplier that he couldn’t deliver mail to his email address.

When I look in the logs I find this:
Mar 26 10:45:26 mail spamdyke[32730]: ALLOWED from: from@allin.nl to: to@update.nl origin_ip: 193.172.164.130 origin_rdns: gw.allin.nl auth: (unknown)

Mar 26 10:45:26 mail qmail-queue-handlers[32750]: recipient[3] = 'from@allin.nl'
Mar 26 10:45:26 mail qmail-queue-handlers[32750]: handlers dir = '/var/qmail//handlers/before-queue/recipient/from@allin.nl'
Mar 26 10:45:26 mail qmail: 1238060726.699923 starting delivery 715: msg 22221538 to remote from@allin.nl
Mar 26 10:45:26 mail qmail-remote-handlers[32752]: to=from@allin.nl

It looks like the qmail-queue-handlers doesn’t understand the mail has to be delivered to in my example to@update.nl . It delivers the mail back to the original sender. When I look in the original mail that bounced back from my server I see this.

I have the feeling that the qmail queue handler thinks he has to deliver the mail to the Reply-to email address and not to the to@update.nl or something like that.
I’m a little bit confused maybe someone has a solution. Because it’s driving me insane.

Thanks in advance,

Ruben
