WMS extent problems

[Andrew Smith]

Hello List,
    I have been working with mapserver for a little while now.  I 
currently have a Linux FC4 box with mapserv 4.6 connecting to a 
Postgres(8.0.1)/PostGIS(1.0) backend.  I have had no trouble 
implementing all the componets, and I am even having success with 
implementing a HTTP front end and am enjoying the experience.  The only 
issue I have had, and have neglected up until now, is the problem of 
extents concerning the dataset described in the mapfile.  I have checked 
the projection (AMG zone 56) using ArcGIS to make sure that I have the 
correct epsg projection (epsg=20256), and it seems right.  So where can 
I go from here.  I have attached a screen shot of a MapInfo connection 
to my WMS, and the corresponding mapfile.  Any suggestions, websites etc 
will be much appreciated.

I have searched the archives of this list, and have found similar 
issues, though no solution has been posted.  So in the spirit of this 
online community, i will post a complete solution when one is obtained, 
including links to resources that helped.

Thanks in advance
