38 Exim is a mail transfer agent (MTA) developed at the University of Cambridge.
39 It is a large program with very many facilities. For a full specification, see
40 the reference manual. This man page contains only a description of the command
41 line options. It has been automatically generated from the reference manual
42 source, hopefully without too much mangling.
44 Like other MTAs, Exim replaces Sendmail, and is normally called by user agents
45 (MUAs) using the path \\fI/usr/sbin/sendmail\\fP when they submit messages for
46 delivery (some operating systems use \\fI/usr/lib/sendmail\\fP). This path is
47 normally set up as a symbolic link to the Exim binary. It may also be used by
48 boot scripts to start the Exim daemon. Many of Exim's command line options are
49 compatible with Sendmail so that it can act as a drop-in replacement.
54 If no options are present that require a specific action (such as starting the
55 daemon or a queue runner, testing an address, receiving a message in a specific
56 format, or listing the queue), and there are no arguments on the command line,
57 Exim outputs a brief message about itself and exits.
59 However, if there is at least one command line argument, \\fB-bm\\fR (accept a
60 local message on the standard input, with the arguments specifying the
61 recipients) is assumed. Thus, for example, if Exim is installed in
62 \\fI/usr/sbin\\fP, you can send a message from the command line like this:
64 /usr/sbin/exim -i <recipient-address(es)>
65 <message content, including all the header lines>
68 The \\fB-i\\fP option prevents a line containing just a dot from terminating
69 the message. Only an end-of-file (generated by typing CTRL-D if the input is
70 from a terminal) does so.
72 .SH "SETTING OPTIONS BY PROGRAM NAME"
75 If an Exim binary is called using one of the names listed in this section
76 (typically via a symbolic link), certain options are assumed.
79 Behave as if the option \\fB\\-bp\\fP were present before any other options.
80 The \\fB\\-bp\\fP option requests a listing of the contents of the mail queue
81 on the standard output.
84 Behaves as if the option \\fB\\-bS\\fP were present before any other options,
85 for compatibility with Smail. The \\fB\\-bS\\fP option is used for reading in a
86 number of messages in batched SMTP format.
89 Behave as if the \\fB\\-i\\fP and \\fB\\-oee\\fP options were present before
90 any other options, for compatibility with Smail. The name \\fBrmail\\fR is used
91 as an interface by some UUCP systems. The \\fB\\-i\\fP option specifies that a
92 dot on a line by itself does not terminate a non\\-SMTP message; \\fB\\-oee\\fP
93 requests that errors detected in non\\-SMTP messages be reported by emailing
97 Behave as if the option \\fB\\-q\\fP were present before any other options, for
98 compatibility with Smail. The \\fB\\-q\\fP option causes a single queue runner
99 process to be started. It processes the queue once, then exits.
102 Behave as if the option \\fB\\-bi\\fP were present before any other options,
103 for compatibility with Sendmail. This option is used for rebuilding Sendmail's
104 alias file. Exim does not have the concept of a single alias file, but can be
105 configured to run a specified command if called with the \\fB\\-bi\\fP option.
