[FreeBSD] Postfix problem -> Recipient address rejected: Domain not found

[BeNe]

Hey Guys,

i started into a new round "ispCP on FreeBSD".
My current problem is still Postfix.

• I´m able to Login via IMAP from the Webmailer
• I can send Mails from user1@domain.tld to user2@domain.tld
• The eMail is moved without any problems to the maildir
  

But i can´t send mails outside in the wide wide World to yahoo for example because of this Error:

Code:

Mar 16 11:49:29 root postfix/smtpd[2022]: connect from unknown[127.0.0.1]
Mar 16 11:49:29 root postfix/smtpd[2022]: NOQUEUE: reject: RCPT from unknown[127.0.0.1]: 450 4.1.2 <my-nick@yahoo.com>: Recipient address rejected: Domain not found; from=<bene2@root.mydomain.tld> to=<my-nick@yahoo.com> proto=ESMTP helo=<admin.root.mydomain.tld>
Mar 16 11:49:29 root postfix/smtpd[2022]: lost connection after RCPT from unknown[127.0.0.1]
Mar 16 11:49:29 root postfix/smtpd[2022]: disconnect from unknown[127.0.0.1]

As i said, from one User to the other on the same Domain it works fine.
Here is the current postfix config:

Code:

root# postconf -n

I checked my DNS-Server of course - but yahoo for example is available for me:

Code:

root# ping yahoo.com

I tried man other Mailadresses with the same result.
