Mail can't be sent to spammer@aol.com or anyone at cyberspammer.com.
! There is also a ``Realtime Blackhole List'' run by the MAPS project
! at http://maps.vix.com/. This is a database maintained in DNS of
! spammers. To use this database, use
FEATURE(`rbl')
! This will cause sendmail to reject mail from any site in the
! Realtime Blackhole List database. You can specify an alternative
! RBL name server to contact by specifying an argument to the FEATURE.
The features described above make use of the check_relay, check_mail,

Mail can't be sent to spammer@aol.com or anyone at cyberspammer.com.
! In addition to the above do-it-yourself spam contol mechanisms, you can also
! enable support in Sendmail for arbitrary combinations of some popular data
! bases of IP addrsses that may try to send spam to your local site via SMTP.
! The list described below are all accessed via a special (kludge?) form of
! DNS lookups.
!
! The first such list is the ``Realtime Blackhole List'' run by the MAPS
! project. Information about this list is available at http://maps.vix.com/rbl/.
! This is a database of the IP addresses of known (fixed) spam sources. To use
! the MAPS RBL list for blocking incoming E-mail, include the line:
FEATURE(`rbl')
! into your .mc file. This will cause Sendmail to reject mail from any IP
! address currently listed in the MAPS RBL database.
!
! Another list that can be used for junk E-mail filtering is the Internet
! Mail Relay Services Survey's (IMRSS) list of unsecured/unrestricted "open"
! E-mail relays. To use the IMRSS list of open relays for blocking incoming
! E-mail, include the line:
!
! FEATURE(`imrss')
!
! into your .mc file. This will cause Sendmail to reject mail from any IP
! address currently listed in the IMRSS open relays database.
!
! Yet another list that can be used for junk E-mail filtering is the DynamicIP
! Spam Sources List (DSSL). This is a list of the IP address of various
! "dynamic" dialup lines, mostly belonging to commercial Internet Service
! Providers and/or Universities. To use the DSSL list of dynamic dialups
! for blocking incoming E-mail, include the line:
!
! FEATURE(`dssl')
!
! into your .mc file. This will cause Sendmail to reject mail from any IP
! address currently listed in the DSSL database.
The features described above make use of the check_relay, check_mail,
