12.3 Configuring the Linux Email System
Many systems use the Sendmail MTA to transfer
email messages
and on many Linux distributions this is
the default Mail Transfer Agent. Sendmail is, however, a complex system
that
can be difficult for both the beginner and experienced user to
understand and
configure. It is also falling from favor because it is considered to be
slower at
processing email messages than many of the more recent MTAs available.
Many system administrators are now using Postfix
or Qmail to
handle email. Both are faster and easier to configure than Sendmail
For the purposes of this chapter we will look at
Postfix as
an MTA because of its simplicity and popularity. If you would prefer to
use
Sendmail there are many books that specialize in the subject and that
will do the subject much more justice than we can in this introduction.
