Hi there, I'm using postfix 2.7.0-1ubuntu0.2 for our main MTA for our company. Last week my manager has send an email to everybody in the company at once. For some users the email bounced because of a quota limit they exceeded. This can be right, but not the bounce message. It said:

Same IP, other emailaddress. Actually this have to be a hostname. Just for your reference, our MTA (Postfix) is in our DMZ. The Zarafa-server (129.50.20.41) is in our trust zone. Why do we get this strange bounce message? If you need more info, please let me know. Kind regards, Roland de Lepper
