In the preceding chapters of this tutorial we developed a minimal client.cf file as an aid in teaching the ins and outs of a small configuration file. In this chapter we show you how to construct a more practical file.
A large part of the V8 sendmail distribution is dedicated to the automated creation of configuration files. Recall (Section 2.1, "Get the Source") that the base sendmail distribution looks like this:
FAQ READ_ME contrib mailstats rmail test KNOWNBUGS RELEASE_NOTES doc makemap smrsh Makefile cf mail.local praliases src
lsREADME domain hack mailer sh cf feature m4 ostype siteconfig
The file README contains all the latest information about the technique that we are about to present. Read it now to get a feel for what is about to happen and to become aware of any late-breaking changes.
Now change into the cf directory and look around.
All the files in it that end in
.mc are m4(1) configuration
source files. Read a few to satisfy your curiosity. We will be creating
our own soon.
