I have been using courier for quite a while, and emails to several

UNDELIVERABLE MAIL

jdsecurity.com.au's Exchange server is broken.
Nothing has changed at our courier end, but there is an error in the log file for the same IP address which says :Jun 22 11:15:01 ver-arc-ms1 courieresmtpd: error,relay=::ffff:202.154.98.58,msg="502 ESMTP command error",cmd: XXXX redhotpie.com.au Jun 22 11:15:11 ver-arc-ms1 courierd: newmsg,id=0002EFE5.4499EF1D.000032BE: dns; redhotpie.com.au (softdnserr [::ffff:202.154.98.58])
And you have a broken Cisco firewall.
