Specify myhostname (http://www.postfix.org/postconf.5.html#myhostname) with a resolvable name on your client or put reject_unknown_helo_hostname after permit_sasl_authenticated on your server. As it might lead to further problems: To match your MAIL FROM to your SASL username set myorigin (http://www.postfix.org/postconf.5.html#myorigin) accordingly. In case of further problems please show the servers postconf -n completely and unaltered. Dennis [..]
