domain where you receive e-mail. Essentially, you need to be
able to install software and/or modify the configuration files
for the Mail Transport Agent on that system.
Although the discussions in this document are conceptual in
nature and can be incorporated into a number of different
MTAs, a sample Exim 4 implementation is provided. This
implementation, in turn, incorporates other software tools,
such as SpamAssassin.
See Appendix A for details.
