matching on inherited attributes

[Maykel Moya <moya-lists@infomed.sld.cu>]

I had created a custom attribute sldMailForwardTo describe mail
recipients for a given alias. As sldMailForwardTo is just an email
address I made it inherits from mail.

The problem is that now, whenever I do a search on mail=foo, entries
having foo on sldMailForwardTo are matched too.

Do exists a way to avoid that? If no, what are the effective benefits
then of having inherited attributes?

Using OL 2.3.38.
