I rebooted the server and now qmail keep giving the above error.
/var/log/qmail/smtpd/current is have this error below:-
@400000004719de3b380f9dac connect(): Connection refused

Probably an old clamd remaining socket; try this sequence:
svc -d /service/clamd
rm /tmp/clamd
svc -u /service/clamd
and check your /var/log/clamd/current log
That fix it.
Thanks
