Are you talking about DNS TTL? Defects or poor programming might reveal
that it's only resolved at service start (like NTP references on IOS), or
possible never cached and DNS is hit for every connection (like SIP trunks
with DNS names in CUCM).

How often does CM query smtp DNS name? we are changing our Cname for SMTP
and would like to know how long I should expect for the emails to change.
Thanks
