I am looking at porting and generalizing an old in-house patch that I'm using for the CMU Sieve plugin. It allows sieve script to test & lookup arguments from LDAP. .. Related work:

1. Pigeonhole low priority TODO would like to implement alternate script storage, eg: LDAP & SQL. I'm not immediately interested in alternate types of script storage, but for what I want to acheive, I need to sanely access at least an LDAP directory.
2. draft-ietf-sieve-external-lists (http://tools.ietf.org/html/draft-ietf-sieve-external-lists-01) proposes a mechanism to pull mailing list addresses from external storage mechanisms such as LDAP, ACAP or relational databases. I'm interested in this, but would like to extend this functionality beyond just lists as the example above demonstrates.

I haven't looked into that draft or thought much about this, but would doing the lookups via Dovecot's lib-dict be ok? That would of course need a dict-ldap backend implemented, but it would be a generic way to solve this, if its API is good enough.
