Well, for sending mails via mail client the problem was, that I forgot to active SMTP Authentication in the client. I guess, that Roundcube suffers from the same problem but also seems to have trouble getting the 'not delivered' E-Mail.

Betreff: [Kolab 3][Debian Wheezy] Emails are receivable but not sendable 

Hi there,

I set up Kolab 3 (I thought I did everything correct, which is apparently not the case), created a few test users, logged in to the roundcube website and tried sending E-Mails. Which does not work. I tried sending them between users on the Kolab system and to users outside the Kolab system. In all cases I get the following errors:

Roundcube: SMTP-Error (454)


/var/log/mail.log

When I try to send an E-Mail from an E-Mail client to an address that is not part of the Kolab system I immediately get an e-mail back which says 

Serverfehler: "554 5.7.1 <targetaddress>: Relay access denied"

/var/log/mail.log
www postfix/smtpd[6164]: NOQUEUE: reject: RCPT from p578bf942.dip0.t-ipconnect.de[87.139.249.66]: 554 5.7.1 <targetaddress>: Relay access denied; from=<foo-bar at servername.de> to=<targetaddress> proto=ESMTP helo=<foobar>

I don't know why I get different error messages (shouldn't they be the same?) or why the e-mail don't get send in the first place.

When I send an E-Mail from an E-Mail client to a user that is part of the Kolab system the email is send without problems.

Receiving E-Mails from outside the Kolab server works just fine.
