NAME¶
Mail::SpamAssassin::Util::RegistrarBoundaries - domain delegation rules
METHODS¶
- ($hostname, $domain) = split_domain ($fqdn)
- Cut a fully-qualified hostname into the hostname part and
the domain part, splitting at the DNS registry boundary.
Examples:
"www.foo.com" => ( "www", "foo.com" )
"www.foo.co.uk" => ( "www", "foo.co.uk" )
- $domain = trim_domain($fqdn)
- Cut a fully-qualified hostname into the hostname part and
the domain part, returning just the domain.
Examples:
"www.foo.com" => "foo.com"
"www.foo.co.uk" => "foo.co.uk"
- $ok = is_domain_valid($dom)
- Return 1 if the domain is valid, "undef"
otherwise. A valid domain (a) does not contain whitespace, (b) contains at
least one dot, and (c) uses a valid TLD or ccTLD.
