that is what I thought - was a bit confused with the recommendation
about a function and LDAP...

I did find a reference from 2003 from Liviu Daia suggesting REGEX
capability in the ldap lookups, but it seems like that was never
discussed outside of that...it was similiar to what I was looking for.

       domain = regexp:/^(.*\.)?my\.domain$/
       query_filter = regexp:/^(.*)$/:(mailacceptinggeneralid=${1})
       result_filter = regexp:/^(.*)$/:${1}
