You should make great care in your regexes to avoid false positives. For example, you cannot receive mails from whirlpool.com with this one. You should probably consider using such a regex only if the host is listed on a dynamic blacklist such as dhcp.tqmcube.com or dynablock.njabl.org. You can also have a look at the regexes spamassassin uses for dynamic IPs.
