[NTLUG:Discuss] Mail server not propagating?

[brian@pongonova.net]

Neil--

A couple of other things.  It looks like you're carrying different SOA records for
the same domain (parasailworkshop.com) on three different nameservers.  This is
sure to cause confusion and mayhem in the world, especially on servers with
brain-damaged caches...please use only one SOA record, and use a serial numbering
scheme that's easy to remember and adjust.  Personally, I use the following on my
servers:

2002061401 
yyyymmddss

where yyyy, mm, and dd represent the date, and ss represents an arbitrary index
number. 

Also, O'Reilly publishes an excellent resource for configuring DNS called "DNS and
BIND."  The only problem I have with the book is BIND :)  But the DNS information
is very good.  Also, consider using djbdns, an alternative to BIND which doesn't
make the consultants that support BIND very happy.  The nice feature of djbdns is
that is splits the caching and name server functionality into two distinct
daemons, rather than the monolithic approach BIND takes.  It's also very
conservative with the host's resources.
