Hi, since I installed my ISPConfig master server using the perfect server tuto, im getting this error everytime I receive an email: Mar 9 17:07:03 master postfix/pipe: 079AA123043: to=<user@domain>, relay=dovecot, delay=440, delays=440/0.01/0/0.03, dsn=4.3.0, status=deferred (temporary failure. Command output: lda: Error: user user@domain: Error reading configuration: Invalid settings: postmaster_address setting not given lda: Fatal: Internal error occurred. Refer to server log for more information. ) Any ideas whats happening? I can login to this mailboxes via webmail without problem. Also I can send throw these mailboxes, but cannot receive.
