To play the devil advocate, many freemail and ISPs specify SPF entries and/or sign mail with DKIM. as a result, some sites will reject mail from such addresses if it fails SPF/DKIM/whatever. Add to that, the client has a "generic hostname": fep\d+.mfe.bur.connect.com.au: $ host 203.63.86.26 26.86.63.203.in-addr.arpa domain name pointer fep06.mfe.bur.connect.com.au. $ host 203.63.86.27 27.86.63.203.in-addr.arpa domain name pointer fep07.mfe.bur.connect.com.au. $ host 203.63.86.29 29.86.63.203.in-addr.arpa domain name pointer fep09.mfe.bur.connect.com.au. > > Guess I need more coffee.
