I expose my problem :
We have an Exchange 2003 server in which all the mailbox for all the company, france and european offices, are set up.
We would like to take out the "out of france" mailbox to a qmail server.
I have correctly managed to setup the relay between Exchange to Qmail. But when i try to send and email from a qmail account to a mailbox that is on the exchange server, as qmail does not know the user it returns me an error :
Hi. This is the qmail-send program at ns380761.ovh.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
I also configured my outlook to use a different smtp server, and it works , the problem is that i do not have any records of the sent mail.
Could someone help me please ?
