[cobalt-users] sendmail problem - user unknown.

["Diana Saunders" <toodi4@xxxxxxxxxxx>]

I've been experiencing a strange problem on a RAQ4 server.  I've seen just a 
few references to something similar both here and in other groups, but no 
explanation that fits the circumstance here.

The problem is that sendmail won't send a message to a certain domain.  In 
my particular the case, the issue came up because a customer was not getting 
mail generated by a php form.

When I ran his address through a test from the command line:

/usr/sbin/sendmail -bv name@xxxxxxxxxxxxxx

I get the response:

name@xxxxxxxxxxxxxx ... user unknown
