I get the following when trying to send email through my courier mail server:

Mar 21 11:46:09 mailbox courieresmtpd: started,ip=[::ffff:192.168.168.101] Mar 21 11:46:09 mailbox courieresmtpd:

From a previous message in the list I saw the sugguestion to check the mx
records: [root@mailbox]# dig hq.knowmadic.com mx

[root@mailbox]# testmxlookup hq.knowmadic.com Hard error.

How come the testmxlookup fails, but dig finds the mx record?
