 Subject:  MX record ability in DNS Forwarder
 Date:  Sun, 18 Jan 2004 22:54:04 -0500
I'm using the static entry capability in m0n0wall's DNS forwarder to 
provide the local IP address of my webserver when clients on the LAN 
query for my website.  For example, the Internet sees daytonawan.com as, however to connect to the webserver from the LAN I need 
to go to  This works fine using the DNS forwarder to 
statically define daytonawan.com as

The problem I am experiencing is as follows.  I'm running a simple SMTP 
server on my LAN, it's purpose is to send messages generated by scripts 
on my webserver.  This works fine, except when I try to send an e-mail 
to myself (@daytonawan.com).  I'm assuming that the SMTP server is 
querying m0n0wall for the daytonawan.com MX record, and when it doesn't 
find one it falls back to the A record (

The mail server handling e-mail for daytonawan.com is not on my LAN, 
it's off at a colo place.  I don't want to use that server as a smart 
host, I want to have my local SMTP server deliver everything directly.  
So, the problem I have is the DNS forwarder doesn't allow me to define 
an MX record, which is what I think I need in this situation.  That 
would allow me to define mail.daytonawan.com as the mail handler for 
daytonawan.com, and since that hostname is not defined in the DNS 
forwarder, it would be looked up in my ISP's name servers and return the 
proper IP address for my incoming mail server.

Sorry if that seems long winded and confusing, but I couldn't find a 
better way to explain it.  So, my question is can a feature be 
implemented in the DNS forwarder to allow for definition of MX records 
in addition to A records?
