me) and say, Good catch.

Thanks for pointing this out. I don't know the details but 1123 says
'
2.1 Host Names and Numbers
The syntax of a legal Internet host name was specified in RFC-952
[DNS:4]. One aspect of host name syntax is hereby changed: the
restriction on the first character is relaxed to allow either a
letter or a digit. Host software MUST support this more liberal
syntax.
Host software MUST handle host names of up to 63 characters and
SHOULD handle host names of up to 255 characters.
'
This suggests that the is_hostname function in plugins/utils.c is wrong
and should be modified accordingly, however I think I should start
shutting up here, because my former comments were _wrong_ (the obsolete
1.2.9 plugins used the incorrect is_hostname() in utils.c) .
The code from this years CVS has is_hostname() in netutils.c and this
uses getaddrinfo() to do gethostbyname_ctx (??).
So to sum up, If you haven't done so already, try the CVS plugin code or
the latest release from SourceForge.
If it doesn't build, post a bug report
If it doesn't work and your resolver is happy with your hostname, post a
bug report.
Sorry for wasting everyones time.

continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'
