I am apparently having an issue with some servers whose mail is being
rejected because of
reject_unknown_hostname
the reject was shown here
Aug 11 00:21:36 xxxxxxx postfix/smtpd[96422]: NOQUEUE: reject: RCPT

but no reject message went out... Is there a way I can esnure an
error message goes out to the sender???
it would also be nice if could cc my postmaster account when rejects
occur
