31.Dt RC.SENDMAIL 8
32.Os
33.Sh NAME
34.Nm rc.sendmail
35.Nd
36.Xr sendmail 8
37startup script
38.Sh DESCRIPTION
39The
40.Nm
41script is used by
42.Pa /etc/rc
43at boot time to start
44.Xr sendmail 8 .
45It is meant to be
46.Xr sendmail 8
47specific and not a generic script for all MTAs.
48It is only called by
49.Pa /etc/rc
50if the
51.Xr rc.conf 5
52.Va mta_start_script
53variable is set to
54.Pa /etc/rc.sendmail .
55.Pp
56The
57.Nm
58script can take an optional argument specifying the action to
59perform.
60The available actions are:
61.Bl -tag -width ".Cm restart-mspq"
62.It Cm start
63Starts both the MTA and the MSP queue runner.
64.It Cm stop
65Stops both the MTA and the MSP queue runner.
66.It Cm restart
67Restarts both the MTA and the MSP queue runner.
68.It Cm start-mta
69Starts just the MTA.
70.It Cm stop-mta
71Stops just the MTA.
72.It Cm restart-mta
73Restarts just the MTA.
74.It Cm start-mspq
75Starts just the MSP queue runner.
76.It Cm stop-mspq
77Stops just the MSP queue runner.
78.It Cm restart-mspq
79Restarts just the MSP queue runner.
80.El
81.Pp
82If no action is specified,
83.Cm start
84is assumed.
85.Pp
86The
87.Nm
88script is also used by
89.Pa /etc/mail/Makefile
90to enable the
91.Pa Makefile Ns 's
92.Cm start , stop ,
93and
94.Cm restart
95targets.
96.Sh RC.CONF VARIABLES
97The following variables affect the behavior of
98.Nm .
99They are defined in
100.Pa /etc/defaults/rc.conf
101and can be changed in
102.Pa /etc/rc.conf .
103.Bl -tag -width indent
104.It Va sendmail_enable
105.Pq Vt str
106If set to
107.Dq Li YES ,
108run the
109.Xr sendmail 8
110daemon at system boot time.
111If set to
112.Dq Li NO ,
113do not run a
114.Xr sendmail 8
115daemon to listen for incoming network mail.
116This does not preclude a
117.Xr sendmail 8
118daemon listening on the SMTP port of the loopback interface.
119The
120.Dq Li NONE
121option is deprecated and should not be used.
122It will be removed in a future release.
123.It Va sendmail_flags
124.Pq Vt str
125If
126.Va sendmail_enable
127is set to
128.Dq Li YES ,
129these are the flags to pass to the
130.Xr sendmail 8
131daemon.
132.It Va sendmail_submit_enable
133.Pq Vt bool
134If set to
135.Dq Li YES
136and
137.Va sendmail_enable
138is set to
139.Dq Li NO ,
140run
141.Xr sendmail 8
142using
143.Va sendmail_submit_flags
144instead of
145.Va sendmail_flags .
146This is intended to allow local mail submission via
147a localhost-only listening SMTP service required for running
148.Xr sendmail 8
149as a non-set-user-ID binary.
150Note that this does not work inside
151.Xr jail 2
152systems, as jails do not allow binding to just the localhost interface.
153.It Va sendmail_submit_flags
154.Pq Vt str
155If
156.Va sendmail_enable
157is set to
158.Dq Li NO
159and
160.Va sendmail_submit_enable
161is set to
162.Dq Li YES ,
163these are the flags to pass to the
164.Xr sendmail 8
165daemon.
166.It Va sendmail_outbound_enable
167.Pq Vt bool
168If set to
169.Dq Li YES
170and both
171.Va sendmail_enable
172and
173.Va sendmail_submit_enable
174are set to
175.Dq Li NO ,
176run
177.Xr sendmail 8
178using
179.Va sendmail_outbound_flags
180instead of
181.Va sendmail_flags .
182This is intended to allow local mail queue management
183for systems that do not offer a listening SMTP service.
184.It Va sendmail_outbound_flags
185.Pq Vt str
186If both
187.Va sendmail_enable
188and
189.Va sendmail_submit_enable
190are set to
191.Dq Li NO
192and
193.Va sendmail_outbound_enable
194is set to
195.Dq Li YES ,
196these are the flags to pass to the
197.Xr sendmail 8
198daemon.
199.It Va sendmail_msp_queue_enable
200.Pq Vt bool
201If set to
202.Dq Li YES ,
203start a client (MSP) queue runner
204.Xr sendmail 8
205daemon at system boot time.
206As of sendmail 8.12, a separate queue is used for command line
207submissions.
208The client queue runner ensures that nothing is
209left behind in the submission queue.
210.It Va sendmail_msp_queue_flags
211.Pq Vt str
212If
213.Va sendmail_msp_queue_enable
214is set to
215.Dq Li YES ,
216these are the flags to pass to the
217.Xr sendmail 8
218daemon.
219.El
220.Pp
221These variables are used to determine how the
222.Xr sendmail 8
223daemons are started:
224.Bd -literal -offset indent
225# MTA
226if (${sendmail_enable} == NONE)
227        # Do nothing
228else if (${sendmail_enable} == YES)
229        start sendmail with ${sendmail_flags}
230else if (${sendmail_submit_enable} == YES)
231        start sendmail with ${sendmail_submit_flags}
232else if (${sendmail_outbound_enable} == YES)
233        start sendmail with ${sendmail_outbound_flags}
234endif
235
236# MSP Queue Runner
237if (${sendmail_enable} != NONE &&
238    [ -r /etc/mail/submit.cf] &&
239    ${sendmail_msp_queue_enable} == YES)
240        start sendmail with ${sendmail_msp_queue_flags}
241endif
242.Ed
243.Pp
244To completely prevent any
245.Xr sendmail 8
246daemons from starting, you must
247set the following variables in
248.Pa /etc/rc.conf :
249.Bd -literal -offset indent
250sendmail_enable="NO"
251sendmail_submit_enable="NO"
252sendmail_outbound_enable="NO"
253sendmail_msp_queue_enable="NO"
