   I'm running into the exact same problem.  My dns is a Win2k server, 
the mail server is FBSD5.3 called kara.home.local.  The dig to 
kara.home.local works fine, but to kara fails.

have you found out any more about why it's not working?  I'm also 
curious about the entry in mailertable because my feeble attempt didn't 
work.

I appreciate any info you can pass on.

Thanks,
Joe.
