some email won't go...

[the lone gunman <lgunman@sewage.debian.org>]

I asked earlier about having an incorrect hostname, and it affecting
emails (i.e. some email doesn't go through).

Here's a copy of a returned email (the references to "sewage" are my
hostname; I have my hostname setup as "sewage"):
