I read the source of sqlgrey.
This is the exactly same as the function added with Rgrey patch.
(http://k2net.hakuba.jp/pub/rgrey-0.2-1.21.tar.gz)
I think the proposal of the same technique by another place to be a very glad.
I think that S25R pattern is the same by the dyn_fqdn.regexp pattern.
And, It is better that there is smtp_server.regexp white list.

I think that the regexp filter should go with postfix(main.cf).
Rgrey had done the regexp filter with (patched)postgrey daemon before.
However, it changed like doing the filter with postfix.
I thought that I was able to decrease the load for the method to pass policy daemon.
