Re: dns firewalls and mx records for internally hosted domains

[hanasaki]

Hi,  no mx records are in the internal server.  I need to leverage the 
external dns as much as possible.  It is a real pain to keep the two 
synchronized with diff IPs for the same hosts and mx's.

You don't mention whether you have input MX records into the internal 
DNS server - do they point to a mail server externally? What is 
generating the 'unroutable address' error - the MUA, or an MTA in the 
path somewhere?
