i'm not sure what options you mean, and we were not using the new
standard sendmail ldap map as we were working on the normal exchange
ldap schema and not using any extra attributes. We were just
validating addresses against searches to exchange for valid user
accounts, and against local aliases to cover mailing lists and
applications. If there was no match on either, it was bounced as we
wanted to reject mail that we didnt have a valid user for, not forward
it on to anything
Im sure there are ways to make it more resilient, this was originally
setup by the guy before me, but i didnt see any reasonable straight
forward way of handling it, other than some complex rulesets
