additional information looking at the logs the emails in question never actually hit the mail server the get filtered and rejected by either expression filter or SBL list list spamhaus. I looked at a few items they get rejected immediately and the few that make it to the Quarantine list are placed there by expression rules. Is it possible since its not attempting to communicate with the server its not being told that the user doesn't exist?You said the mail is being placed there by expression filters..take out the expression filters in question and try again. I don't use AD callout..i use regular callout. if you use AD collout every internal user has to have a matching external e-mail address or ad callout won't work at all.
