Configuring sendmail to use the RealTime Blackhole list
Sendmail is able to use the services of the RealTime Blackhole List. The
Blackhole List, a list of known spam domain names, is maintained by an
organization called MAPS (Mail Abuse Prevention System). The mail server
checks each mail message against the Blackhole list. Any e-mail message
originating from a domain in the list will be rejected.
Note: You must subscribe to the MAPS Blackhole List in order to use it. Go to
www.mail-abuse.com for details.
To configure the Sidewinder G2 to use the Realtime Blackhole List, follow the
steps below.
1 Log into the Admin Console and select Services Configuration > Servers.
2 Select sendmail and click the Configuration tab. Separate configuration
files are maintained for each burb.
3 Select the M4 Config File in the external burb list and click Edit File.
4 Add the following line to the file.
FEATURE(‘dnsbl’, ‘hostname’)dnl
The hostname that you enter in the above line will depend on the type of
service for which you have subscribed. MAPS will provide you with the correct
hostname (for example, blackholes.mail-abuse.org) to use when you
subscribe to their list.
