Hello I almost forgot that, here a local ISP (and the biggest) Hinet uses primarily subdomain as the mail address for its users.
for example, $ for i in `seq 11 19`;do dig ms$i.hinet.net mx +nocmd +noall +answer;echo;done ms11.hinet.net. 86263 IN MX 0 msx-smtp-mx1.hinet.net. ms11.hinet.net. 86263 IN MX 0 msx-smtp-mx2.hinet.net. ms12.hinet.net. 86336 IN MX 0 msx-smtp-mx1.hinet.net. ms12.hinet.net. 86336 IN MX 0 msx-smtp-mx2.hinet.net. ms13.hinet.net. 86337 IN MX 0 msx-smtp-mx1.hinet.net. ms13.hinet.net. 86337 IN MX 0 msx-smtp-mx2.hinet.net. ms14.hinet.net. 86337 IN MX 0 msx-smtp-mx1.hinet.net. ms14.hinet.net. 86337 IN MX 0 msx-smtp-mx2.hinet.net. ms15.hinet.net. 86269 IN MX 0 msx-smtp-mx1.hinet.net. ms15.hinet.net. 86269 IN MX 0 msx-smtp-mx2.hinet.net. ms16.hinet.net. 86338 IN MX 0 msx-smtp-mx2.hinet.net. ms16.hinet.net. 86338 IN MX 0 msx-smtp-mx1.hinet.net. ms17.hinet.net. 86337 IN MX 0 msx-smtp-mx1.hinet.net. ms17.hinet.net. 86337 IN MX 0 msx-smtp-mx2.hinet.net. ms18.hinet.net. 86337 IN MX 0 msx-smtp-mx2.hinet.net. ms18.hinet.net. 86337 IN MX 0 msx-smtp-mx1.hinet.net. ms19.hinet.net. 86296 IN MX 0 msx-smtp-mx2.hinet.net. ms19.hinet.net. 86296 IN MX 0 msx-smtp-mx1.hinet.net. They have dozens of this kind of domains. But, all those subdomains have no zone defined. And, hinet.net is not listed into PSL from the query here: https://publicsuffix.org/list/public_suffix_list.dat I don't think those addresses can't send messages to yahoo/kimo mailbox. regards, Ken Peng _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
