Hey guys,
first of all: I hope this is the right part of the forum. If not, just move this thread, dear mods ;-)
I am struggling with a serious issue and just cant find a solution. I have set up Ubuntu 16.04 on one of our company's server (an old one for testing purposes since I am a trainee) to test out the groupware software ZIMBRA. The installation went fine and I also configured all the necessarry things like hosts, networks and DNS. I can send mails between the ZIMBRA host and our network and telnet also works fine. The problem appears when I try to send a mail to an unknown receiver.
Lets say we have 2 domains: @123.de (company domain) and @abc.de (ZIMBRA domain I received from our sysadmin for testing purposes). The @abc.de domain was in use some years ago and some addresses are still in use, circulating "through the web". Since ZIMBRA uses Postfix as the MTA, I found out that there are 2 options:
luser_relay and local_recipient_maps
The first one defines a static email address where all the mails from all addresses with the @abc.de domain are merged so that none of the potential addresses in use gets lost. Lets call that one
dump@abc.de => for example, when I send a mail from
user@123.de to
xyz@abc.de (non existent address) to test whether the mail is being collected by
dump@abc.de, I get the DSN=5.0.0 error. The mail is getting bounced and deferred to the senders working address (@123.de). I have tried every solution offered by ZIMBRA and/or postfix and many other forums.
Does anyone have an idea? I will post the mail.log!

The MTA accepts the mail, queues it and before delivering it, it gets bounced. I am really desperate!
Postfix DSN=5.0.0 (domain.com) status=bounced
