The use of LDAP is becoming increasingly popular, and the demand for mail transfer agents (MTAs) to be able to extract relevant information is increasing along with it.  Of particular interest is settling upon a common schema for local email routing.  LDAP will *not* be contacted for routing e-mail until the MTA first determines that it is listed as an MX or A record for the host named on the right hand side of the email address.  The goal is to define which schema to use in requesting local routing information (a.k.a. aliasing) from an LDAP directory service. There are currently no such standards-track specifications under review in the IETF.  There is draft-lachman-ldap-mail-routing-03.txt, which is on track to become an Informational RFC; parts of this may be a good start at a standards-track specification (the focus here is narrower than in that draft). But competing proposals exist (I know of at least one I-D in the works), so the time seems right for a BOF to discuss whether an existing proposal is ready to move forward or if a working group is merited.  I therefore propose that such a BOF be held at the Orlando IETF meeting.
