Hmm...  One obvious possibility is that "test" is already a legitimate
user id or global or personal alias on your system.  Another possibility
is that you've got AMS_OnlyMail: 1 set in your configuration, though I
don't *think* that would explain this one.   Another possibility is that
you don't have your *.mspath preference right.

I suggest trying the following:  Run the cui program and type:

set level wizard
set term 0
set debug 0 0 0 -1
whois test

The "whois" command is simply a test/probe into the address validation
routines.  Doing this with messagserver debugging turned on will produce
some voluminous output.  If the output doesn't make the problem clear,
then you could at least post the output to this mailing list and it is
more likely that someone will be able to diagnose it better.  Good luck.
