Re: [cobalt-users] Raq 550 Moved - receives no email

["Ted" <ted@xxxxxxxxxxxxxxx>]

I have seen this as well when propagation was delayed by a long DNS change
over time.
I would do an internal test and send mail to the server to make sure it is
accepting mail
and record the logs in one screen using tail -f /var/log/syslog or maillog
which ever applies.

The I would have someone do the same thing externally from the network and
see what the
log file states. See if it ever talks to the server.

see what your SOA refresh is set at. this will tell you when the world will
see your changes.

SOA REFRESH value : here is the basic info from dnsreports.com on this issue
.

WARNING: Your SOA REFRESH interval is : 16384 seconds. This seems a bit
high. You should consider decreasing this value to about 3600-7200 seconds.
RFC1912 2.2 recommends a value between 1200 to 43200 seconds (20 minutes to
12 hours; 12 hours seems very high to us), although some registrars may
limit you to 10000 seconds or higher, and if you are using DNS NOTIFY the
refresh value is not as important (RIPE recommend 86400 seconds if using DNS
NOTIFY). This value determines how often secondary/slave nameservers check
with the master for updates. A value that is too high will cause DNS changes
to be in limbo for a long time.

This last sentence basically stated that because your DNS service has such a
high number DNS changes take longer than normal. Hope this helps!
