Attribute value rewriting

So I have an interesting issue, and I'm wondering if there's an easy solution (although I'm guessing it would take slapo-rwm reworking).

Basically, email id's can come in the form of


(basically, any combination of periods and hyphens).  My own data is:

lsearch uid=quanah suseassunetid
dn: uid=quanah,cn=accounts,dc=stanford,dc=edu
suSeasSunetID: qgibsonmount
suSeasSunetID: quanah
suSeasSunetID: quanahgibsonmount

which means that any form of quanah@stanford.edu, qgibsonmount@stanford.edu, and quanahgibsonmount@stanford.edu are deliverable.

In our directory, we store what we consider the normalized form (all periods and hyphens stripped out). What I'd like is a way to make sure that any incoming filter request for the attribute (suseassunetid) strips the value(s) of periods and hyphens before the query is evaluated.
