Please do not flame me if this is a FAQ or an obviously stupid question.
I have looked for the answer, I do not read this newsgroup on a regular basis
and have not been able to find a FAQ or an archive to search thru.  
Any  help will be greatly appreciated!!!

1) I am looking for a good source on DNS, books or articles or newsgroups.

2) If possible, I am trying to set our site up so that we do not have to 
   have individual MX records for machines just subdomains. 

   The following wildcard does not work for hosts inside our domain 
   if they have an A record but not an MX entry in the DNS. Yet the
   lookup works for hosts that do not have an A record:
   This problem is compounded by the problem that in non-literal
   lookups the domain name is appended twice.   
 
Here is the wildcard entries in our DNS file

bms.com.        IN      MX      10      cliff.bms.com.
*.bms.com.      IN      MX      10      cliff.bms.com.
*               IN      MX      50      dino.bms.com.

Here is the example of an MX  query for a host with an
address record in the DNS but not an MX.  

>vicster
Server:  horta.bms.com
Address:  140.176.4.31

*** No mail exchanger (MX) records available for vicster

> vicster.bms.com.
Server:  horta.bms.com
Address:  140.176.4.31

*** No mail exchanger (MX) records available for vicster.bms.com.

> vicster.bms.com
Server:  horta.bms.com
Address:  140.176.4.31

vicster.bms.com.bms.com preference = 10, mail exchanger = cliff.bms.com
vicster.bms.com.bms.com preference = 50, mail exchanger = dino.bms.c 


Here is an example of an MX query for a host that doesnot have
any entry in the DNS

> foo
Server:  horta.bms.com
Address:  140.176.4.31

foo.bms.com     preference = 10, mail exchanger = cliff.bms.com
foo.bms.com     preference = 50, mail exchanger = dino.bms.com
cliff.bms.com   internet address = 140.176.0.102
dino.bms.com    internet address = 140.176.4.30

> foo.bms.com.
Server:  horta.bms.com
Address:  140.176.4.31

foo.bms.com     preference = 10, mail exchanger = cliff.bms.com
foo.bms.com     preference = 50, mail exchanger = dino.bms.com
cliff.bms.com   internet address = 140.176.0.102
dino.bms.com    internet address = 140.176.4.30

> foo.bms.com
Server:  horta.bms.com
Address:  140.176.4.31

foo.bms.com.bms.com     preference = 10, mail exchanger = cliff.bms.com
foo.bms.com.bms.com     preference = 50, mail exchanger = dino.bms.c

Thank you in advance!
