the problem is that nearly all clients are only display the LAST respsonse-line which is as example currently a real problem with "smtpd_reject_footer" because the user wil never see anything except the footer, AFAIK the will be the possiblity on postfix 2.10 to add the reject-footer without a new line to solve this i had this last week again where i customer did not understand the error message (which contained only the request footer) and a look in the maillog showed me that "reject_non_fqdn_recipient" was the (correct) reason "Recipient address rejected: need fully-qualified address"
