+      <para>On Linux, any Sendmail-compatible MTA (Mail Transfer Agent) will suffice.
+      Sendmail, Postfix, qmail and Exim are examples of common MTAs. Sendmail is the 
+      original Unix MTA, but the others are easier to configure, and therefore many people
+      replace Sendmail with Postfix or Exim. They are drop-in replacements, so that Bugzilla
+      will not distinguish between them.</para>

+      <para>Consult the manual for the specific MTA you choose for detailed installation
+      instructions. Each of these programs will have their own configuration files where you must
+      configure certain parameters to ensure that the mail is delivered properly. They
+      are implemented as services, and you should ensure that the MTA is in the
+      auto-start list of services for the machine.</para>
