Sure.. it's quite trivial anyway.. See attached diff -u patch.

By the way, if you've got the patch, the following ACL will greylist hosts 
which are unresolvable and get sent down by sendmail as a bracketed IP 
instead of a hostname.

#greylist unresolvable hosts
acl greylist domain /\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\]/

The same could be done with the non-extended regexes, but the syntax is a 
bit different. To start with you'd need \{1,3\} instead of {1,3}.
