I seem to remember this has something to do DNS… I know if the box is running 
its own BIND, then restart bind [ranges from “/etc/rc.d/init.d/named restart” 
to systemctl restart named).

Hi:

We see entries like this in the qmail/send log when clients try to send to a 
particular domain:

2018-01-18 14:49:03.821437500 starting delivery 93767: msg 21453716 to remote 
mvelasq...@prevenir.com.ec <mailto:mvelasq...@prevenir.com.ec> 
2018-01-18 14:49:39.016795500 delivery 93767: deferral: 
CNAME_lookup_failed_temporarily._(#4.4.3)/


Does anyone know what this entry is trying to tell us? and what would a CNAME 
lookup have to do with sending email?

Jeff
