The initial behavior of sendmail is determined largely by the command line used to invoke it. The command line can, for example, cause sendmail to use a different configuration file or to rebuild the aliases file rather than deliver mail. The command line can be typed at your keyboard, executed from a boot-time script, or even executed by an MUA when sending mail. The format of the sendmail command line is: argv[0] switches recipients Here, argv[0] is the name used to run sendmail . The switches , if any are present, must always precede the list of recipients. The recipients is a list of zero or more recipient address expressions. |
