X-LCID: 6252

For the last connection IP,it is better to add rDNS record,it is useful for header filter,for example,Received header contains: .dynamic.  Add score on it.

This is a good suggestion and we will add it in.

However, looking for the word 'dynamic' is probably not the best way to determine if the message is originating from a dynamic IP address. Xeams already has a filter that looks and assigns a score if a message comes from a dynamic address.

It is just an example,sometimes,it is very useful,such as i can add score for below rDNS:

xxxx.dynamic.163data.com.cn

xx-xx-xx-xx.hostwindcloud.com

xxx.dailup.xxxx

These IP has default  RDNS,but not customer's domain.
