Testing the m4 Configuration:
Test the new configuration using the sendmail –bt command exactly as it was used earlier in this
chapter. The following listing shows a test of the linux.cf file that we built with m4 macros.
# sendmail -bt -Clinux.cf
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>
> /tryflags HS
> /try smtp craig

This time, when the sender address craig is processed through the Extended SMTP mailer, the
address is rewritten to craig.hunt@foobirds.org using the genericstable database that we created.
Again, after running several tests, copy linux.cf to /etc/sendmail.cf.
Of course, this entire configuration depends on having the m4 source files on the Linux system. If your system doesn't have the m4 source files, you can download the latest sendmail distribution from ftp://ftp.sendmail.org/, where it is stored in the pub/sendmail directory. The distribution includes a complete sendmail m4 source tree.
