How can we make a postfix delete or quarantine OUTGOING emails based on the following criteria:

Delete if FROM address is <> or MAILER-DAEMON "and" TO address user domain donít exist in Local Domains list hosted by Zimbra.

Point is we donít want to send postmaster return mails to outside users but only to users hosted by zimbra.

i.e: if mailbox of a user is full then Zimbra will try to send email back to sender using MAILER-DAEMON or <> then we like to stop this unless its going internally to Zimbra domain user only
