Hello Willem

The bounce message:
/var/log/maillog:May 30 15:57:56 mail postfix/smtpd[1667]: NOQUEUE: reject:
RCPT from ctb-mesg-2-2.saix.net[196.25.240.87]: 450 <noshc(at)telkomsa.net>:
Sender address rejected: unverified address: Address verification in
progress; from=<noshc(at)telkomsa.net> to=<jonfinescrap.co.za> proto=ESMTP
helo=<ctb-mesg-2-2.saix.net>

I know that ctb-mesg-2-2.saix.net is a relay out only for an telkomsa.net

Dig mx on the senders domain telkomsa.net.
305 IN MX 10 mail.telkomsa.net

So I manually checked that the email address exists..
telnet mail.telkomsa.net 25
Trying 196.25.211.150...
Connected to mail.telkomsa.net.
Escape character is '^]'.
220 telkomsa.net ESMTP Welcome to the TelkomSA SMTP Server.
ehlo mail.finescrap.co.za
250-telkomsa.net Welcome to the TelkomSA SMTP Server.

mail from: jon(at)finescrap.co.za
250 ok
rcpt to: noshc(at)telkomsa.net
250 ok

hmm... what am i missing?
here is my sender verification config.

smtpd_sender_restrictions = reject_unknown_sender_domain,
        hash:/etc/postfix/access,
        permit_mynetworks,
        check_sender_access hash:/etc/postfix/domain.whitelist,
# warn_if_reject reject_unverified_sender,
        reject_unverified_sender,
# address_verify_map = btree:/var/spool/postfix/verify

Kind Regards
Brad
