LDAP / MTA integration

["Paul Makepeace" <makepeace@houston.cwomnes.net>]

The UIUC who produced the 'qi' suite (PH query interpreter) bundle a neat
program called phquery which trys to figure out someone's email address
given an alias by doing fuzzy queries against a PH server using PH name &
alias.  phquery also tries tricks like remapping . (dot) to _ (underscore)
to help. It's discussed at:

    http://www-wsg.cso.uiuc.edu/sendmail/UIUCnet/phquery.html

There's a sendmail map patch too that's discussed that doesn't involve
phquery reinvoking sendmail to perform the resolved-delivery (I can't figure
out whether it does the fuzzy matches either, such is my lack of knowledge
about sendmail!). That's at:

    http://www-wsg.cso.uiuc.edu/sendmail/sendmail-phmap/

I would like to replicate this technique but using LDAP. It seems that it's
not been done, at least not including the fuzziness and punctuation
rewriting which has made it very useful. Does anyone know of a similar
program to this that uses LDAP?

I've found the following resources that are related but not quite what's
needed: Booker Bense's technique for converting a finite set of 'mail
accepting ids' into a rfc822 maildrop:

This also includes a link for the the Stanford approach to resolving CN's
into email addresses:

I'm looking at this from a development point-of-view: any info/code I can
get before I implement this would be muc appreciated.

Thanks, Paul.
