    Administrators of mail servers

    We recommend administrators of mail servers under Linux / FreeBSD, those who use MTA sendmail, to apply anti-spam filters SPAMCOP, ORDB and JINR-BL. For this, add the following lines to sendmail.mc

    FEATURE(blacklist_recipients)
    FEATURE(`dnsbl', `bl.jinr.ru', `"550 Spam blocked from " $&{client_addr} " - see https://noc.jinr.ru/spam-ip.html "')
    FEATURE(`dnsbl', `relays.ordb.org', `"550 Spam blocked - see http://ordb.org/"')
    FEATURE(`enhdnsbl', `bl.spamcop.net', `"Spam blocked see: http://spamcop.net/bl.shtml?"$&{client_addr}', `t')

    Then compile sendmail.cf and restart it.

    The JINR-BL database is supported by the JINR Network Service.
