The allowed character set for domain names is specified in one of the
RFCs to be letters, digits, the hyphen ("-"), and (for separating
fields only), the period ("."). (Sorry, I don't remember the RFC
number offhand, look in the BIND source distribution CHANGES file.)
BIND enforces this, but some nameserver software doesn't. Every once
in awhile someone puts an underscore in a hostname or subdomain and
discovers that many sites - those requiring that a domain name be
resolvable - will no longer accept their mail.
