   在SORBS网站提供的排除DUHL的条件(http://www.dnsbl.au.sorbs.net/faq/dul.shtml)是这样的:
The MX record of a domain needs to contain a host name that maps to the IP address involved. The Time to Live of the MX record needs to be at least 43200 seconds.(域名的MX记录包含一个主机名,并指向IP地址.MX记录的在线时间需要是最近的43200秒前.)The A record for the host name needs to have a TTL of at least 43200 seconds. (最近的43200秒前,主机名的A记录,需要有一个TTL值)The reverse DNS PTR record for the IP address involved needs to map back to the name given in the MX record, and to have a TTL of at least 43200 seconds. (IP地址所指的反向DNS PTR记录,需要指回所使用的MX记录.并且最近的43200秒前.有一个需要有一个TTL值)If there are multiple MX entries, these rules apply to them all. (如果存在多个MX,都必须适用上面的条件)
