have configured postfix to query the ldap server to verify email addresses as follows: local_recipient_maps = hash:/etc/postfix/aliases,ldap:ldap-usermap unknown_local_recipient_reject_code = 450

The problem is if the ldap servers are unavailable postfix rejects all email without queuing for retry. Is it possible to configure postfix to defer delivery of any email when the ldap servers are offline.

These messages are coming from outside, right? If so, this is correct behavior. The 450 code (I think; you can look it up) says something about deferred, try later. Correctly configured remote servers should try again later.
