$ host 0.0.0.0
Host not found.
$ host 0.0.0.0.in-addr.arpa
Host not found.

-- typically, unless your reverse-DNS is broken in some
spectacularly creative way, INADDR_ANY won't have a name
associated with it.

The simplest way to fix this is to set the domain
explicitly.

uname(2) also has a field for domainname. On many of my
machines, this is blank, but I suppose that tpop3d could
use it if non-blank. However, I suspect that it would be
`more correct' to use the full domain name (node name .
domain name) of the system in this scenario. I'm open to
reasonable suggestions and patches, as ever, but this is
probably too trivial a point to worry over unduly.

Is tpop3d.conf(5) unclear on how the listener: directive
is used?
