[sigh] Claude, you really should read the advice given here -
particularly that having to do with specific details and directions -
carefully. I realize that you've got a shoulder injury, etc. distracting
you, but computers aren't forgiving: either you do the right thing, or
they don't work the way you want them to.
 
What I wrote was, "just change [the hostname] in your '/etc/hostname' and
'/etc/hosts' files." You skipped the first (crucial) part, followed the
second (important but not critical) part, and aren't getting the results
you want. The only surprising thing is that you find it surprising.

Here's a great hint for that entire meta-category of decisions: when you
have difficulty choosing one of a range of options, that means that the
options are similar enough that it doesn't matter. In other words,
choose any one of them; it won't make that much of a difference.

This is particularly true here, since all nullmailers do essentially the
same thing. Some feature variations do exist, but if you find that you
just can't live without feature X later, switching to another nullmailer
is just as trivial as installing one in the first place - and you'll
have learned a bit more about nullmailers by that point, which will make
it easier yet.

As Good As Any(tm). :)
