need help with setting LDAP search domains

Hi - I have set up LDAP search queries for delivering mail. The queries appear to be working correctly however, when checking the LDAP logs I am seeing queries for any domain that mail is sent. (In the logs, it also appears that the queries are being re-run, after the completion of a successful

Re: problem with protection.outlook.com released spam getting bounced

Postfix reports this error because it is responsible for 'example.com' and the message has 'Delivered-To: u...@example.com'. There are several options: 1) Your error. Your system is sending mail out after adding the 'Delivered-To: u...@example.com' header, and it comes back from outlook.com. If
