Default Relay access denied when using SMTP to external recipients

Unable to send emails to any domains not hosted locally on this server via SMTP client. If I do the same using SMTP client I receive NDR and below message in my /var/log/maillog.

Oct 10 12:12:12 portal postfix/smtpd[9641]: NOQUEUE: reject: RCPT from gateway[]: 554 <>: Relay access denied; from=<> to=<> proto=ESMTP helo=<Inbox>

Everything works fine if I use web mail client UebiMiau except UebiMiau translates internal emails to But at it lets me send emails to without any problem, see the log message below which works perfectly.

Oct 10 12:25:32 portal postfix/smtp[9943]: 78FFA485C8E: to=<>,[], delay=23, status=sent (250 ok dirdel)

I have read few threads where people are facing this error "Relay access denied" but couldn't really find the resolution for my problem.

I have perfectly installed ISPConfig on FC4 without any problems. /etc/postfix/ has following entry as per installation instruction. I have tried check_relay_domains appears same after restarting postfix.

smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject _unauth_destination
