You might be able to do this with a PCRE in smtpd_recipient_restrictions. These however usually trigger on a single match, and you need to trigger on strictly a double match. I'm no regex expert. Maybe someone here can help you out. This issue relates to a single user. Is there a reason why you can't merely implement this as an MUA rule? MTAs usually deal with site wide mail issues, not individual email address rules. If you have a problem user whom you are attempting to take disciplinary action against, I suggest that attempting to use Postfix to deprive that user of his/her Facebook email is not the best way to accomplish this goal. Employee/student behavioral problems can only be properly addressed by management or administration policy and action. Many schools and businesses null route social networking sites' IP ranges at the edge, denying _everyone_ access to said sites. The reason being that this type of social networking should not be stealing time from the classroom or workplace. -- Stan
