In the following, we will refer to it as sendmail.m4. <P> This file contains a few definitions and otherwise merely points to the tables where the real work gets done. In general, it is only necessary to specify: <P> <UL><LI> the pathnames and filenames used on the local system.<LI> the name(s) the site is known by for e-mail purposes.<LI> which default mailer (and perhaps smart relay host) is desired. </UL> <P> There are a large variety of parameters that can be defined to establish the behavior of the local site or to override compiled-in configuration items. These configuration options are identified in the file ida/cf/OPTIONS in the source directory. <P> A sendmail.m4 file for a minimal configuration (UUCP or SMTP with all non-local mail being relayed to a directly connected smart-host) can be as short as 10 or 15 lines excluding comments. <P> <BR> <HR> <UL> <LI> <A HREF="node222.html#SECTION0017310000">An Example sendmail.m4 File</A> <LI> <A HREF="node223.html#SECTION0017320000">Typically Used sendmail.m4 Parameters</A> <UL> <LI> <A HREF="node224.html#SECTION0017321000">Items that Define Paths</A> <LI> <A HREF="node225.html#SECTION0017322000">Defining the Local Mailer</A> <LI> <A HREF="node226.html#SECTION0017323000">Dealing with Bounced Mail</A> <LI> <A HREF="node227.html#SECTION0017324000">Domain Name Service Related Items</A> <LI> <A HREF="node228.html#SECTION0017325000">Defining Names the Local System is Known by</A> <LI> <A HREF="node229.html#SECTION0017326000">UUCP-Related Items</A> <LI> <A HREF="node230.html#SECTION0017327000">Relay Systems and Mailers</A> <LI> <A HREF="node231.html#SECTION0017328000">The Various Configuration Tables</A> <LI> <A HREF="node232.html#SECTION0017329000">The Master Sendmail.mc File</A> <LI> <A HREF="node233.html#SECTION00173210000">So Which Entries are Really Required?</A> </UL> </UL> <BR> <HR> <P><ADDRESS> <I>Andrew Anderson <BR> Thu Mar 7 23:22:06 EST 1996</I> </ADDRESS> </BODY> </HTML>
