You cannot spam "all accounts". You can only try to send spam to addresses you are knowing or guessing.
Unfortunely, sendmail is (and was before me) the mail system.
I don't think that other programs will handle this much better than sendmail.
Diagnostic-Code: 550 5.2.1 <abuse@hinet.net>... Mailbox disabled for this recipient.
That should be the correct address for complaints to hinet.net, but unfortunately HINET violates RfC 2142 rejecting mails sent to abuse@hinet.net or postmaster@hinet.net (as one can see on http://www.rfc-ignorant.org). You could write to network-adm@hinet.net or cykang@ms1.hinet.net (these addresses I found by "whois -h whois.apnic.net 61.224.129.145"). But sending complaints to China or Taiwan is almost the same as sending them directly to /dev/null. As a solution you could block all HINET IPs by your access table. Or better: all IPs in Korea, Taiwan and China - if you don't expect any wanted mails from this countries. Or you use the FEATURE(`dnsbl') of sendmail to block all known spammer IPs. More information about that you can find on http://www.sendmail.org/~ca/email/chk-810.html. Bye, Hatto
