.SH REPLACEMENT PATTERNS
137
.B update\-exim4.conf
138
know about these identifiers:
140
.I DEBCONFconfigtypeDEBCONF
141
dc_eximconfig_configtype in /etc/exim4/update\-exim4.conf.conf.
143
.I DEBCONFheaders_rewriteDEBCONF
144
If the system is configured to hide the system mail name, this is
145
replaced with a headers_rewrite directive rewriting sender addresses
146
from local domains to the visible mail name for use on the transport
147
that sends outgoing mail to the smarthost.
149
.I DEBCONFlistenonpublicDEBCONF
150
This is replaced with
151
\(lqlocal_interfaces = <value of dc_local_interfaces>\(rq if
152
dc_local_interfaces is set to a non-empty value. Otherwise, it is
153
replaced with an empty string, causing the exim SMTP listener daemon
154
to listen on all local interfaces.
156
If dc_local_interfaces is set to a non-empty value, this will cause
157
the exim SMTP listener daemon to listen only on the IP addresses
158
listed in the option.
160
.I DEBCONFlocaldeliveryDEBCONF
161
is replaced by the contents of dc_localdelivery in
162
/etc/exim4/update\-exim4.conf.conf. It should be set to the default
163
transport for local delivery, i.e. usually mail_spool or maildir_home. It
164
defaults to mail_spool if dc_localdelivery is unset.
166
.I DEBCONFlocal_domainsDEBCONF
167
is internally generated from the contents of dc_other_hostnames in
168
/etc/exim4/update\-exim4.conf.conf and localhost.
170
.I DEBCONFminimaldnsDEBCONF
171
is replaced with \(lqDC_minimaldns = 1\(rq if dc_minimaldns is set to true
172
and to an empty string otherwise.
174
.I DEBCONFnever_usersDEBCONF
175
is deleted. (In versions prior 4.30-7 it was used to set the never_users
178
.I DEBCONFpackageversionDEBCONF
179
contains the complete Debian version-number of the exim4\-config
180
package. You could use this in smtp_banner or received_header_text.
182
.I DEBCONFreadhostDEBCONF
183
corresponds to dc_readhost in /etc/exim4/update\-exim4.conf.conf and holds
184
the visible mailname for satellite\-systems.
186
.I DEBCONFrelay_domainsDEBCONF
187
is replaced by the contents of dc_relay_domains in
188
/etc/exim4/update\-exim4.conf.conf
190
.I DEBCONFrelay_netsDEBCONF
191
is replaced by the contents of dc_relay_nets in
192
/etc/exim4/update\-exim4.conf.conf
194
.I DEBCONFreturn_pathDEBCONF
195
If the system is configured to hide the system mail name, this is
196
replaced with a return_path directive setting the return path domain
197
name to the visible mail name for use on the transport that sends
198
outgoing mail to the smarthost.
200
.I DEBCONFrewriteemailaddresses_mailnameDEBCONF
201
is replaced with this rewriting rule:
203
*@\fImailname\fR ${lookup {${local_part}} lsearch {/etc/email-addresses} {$value} fail } Ffrs
205
with \fImailname\fR being replaced by the contents of /etc/mailname.
207
.I DEBCONFsmarthostDEBCONF
208
corresponds to dc_smarthost in /etc/exim4/update\-exim4.conf.conf and
209
contains the name (and Port) of the SMTP smarthost that takes care of
212
.I DEBCONFvisiblenameDEBCONF
213
holds the contents of (the first line of) /etc/mailname
215
.I DEBCONF_hardcode_primary_hostname_DEBCONF
216
If dc_minimaldns is set to true
217
.B update\-exim4.conf
218
tries to guess the primary hostname using hostname \-\-fqdn and replaces
219
this pattern with \(lqprimary_hostname = <guessed value>\(rq.
221
142
.SH CONFIGURATION VARIABLES
143
All lists given in configuration variables are semicolon-separated. In
144
the past, they used to be colon separated. This was changed to
145
semicolon separation to make specification of IPv6 addresses easier.
146
Backwards compatibility is preserved, so that old configurations using
147
colons as separators do still work. Colons are deprecated and might
148
stop working in a later release. If you need to specifiy a single IPv6
149
address in a field that are defined as a list of host names or IP
150
addresses, please prefix "<;" to explicitly specify the list separator
151
as a semicolon. Otherwise, the code cannot tell an IP address from a
152
colon-separated list of strange host names.
154
Using lookups like "dsearch;something" in update-exim4.conf.conf has
155
never been supported and does no longer work! If you need this, please
156
convert to directly setting the appropriate macros.
222
158
.B update\-exim4.conf
223
159
evaluates these patterns in
224
160
.B /etc/exim4/update\-exim4.conf.conf:
229
165
.I dc_eximconfig_configtype
230
166
The main configuration type. One of \(lqinternet\(rq, \(lqsmarthost\(rq,
231
167
\(lqsatellite\(rq, \(lqlocal\(rq, \(lqexim3manual\(rq or \(lqnone\(rq.

Sets macro DC_eximconfig_configtype.
233
170
.I dc_hide_mailname
234
171
Boolean option that controls whether the local mailname in the headers of

outgoing mail should be hidden. (Only effective for \(lqsmarthost\(rq and
173
\(lqsatellite\(rq. Sets macro HIDE_MAILNAME.
238

.I dc_mailname_in_oh

Internal use only Boolean option that is set by the maintainer scripts
240
177
after adding the contents of /etc/mailname to the dc_other_hostnames
241
178
list. This is a transition helper since it wouldn't otherwise be
242
179
possible to see whether that domain name has been removed from
243
dc_other_hostnames on purpose.

dc_other_hostnames on purpose. This is not used by update-exim4.conf,

.I ue4c_keepcomments
246
184
Boolean option that controls whether
247
185
.B update\-exim4.conf
248

249
187
leaves them in. This can be overridden by the command line options
250
--keepcomments and --removecomments.
188
--keepcomments and --removecomments. The value is not written to an

.I dc_localdelivery
253
192
name of the default transport for local mail delivery. Defaults to mail_spool
254
if unset, use maildir_home for delivery to ~/Maildir/. This setting
255
does not correspond to a Debconf question and needs to be set manually.
193
if unset, use maildir_home for delivery to ~/Maildir/. Sets macro
257
196
.I dc_local_interfaces
258
Used as the value for
260
main configuration option local_interfaces. If the string contains a
261
semicolon, the string \(lq<;\(rq is prepended to select the semicolon

List of IP addresses the Exim daemon should listen on. If this is left
198
empty, Exim listens on all interfaces. Sets macro

285
A list of machines for which we serve as smarthost. Used to

populate the relay_from_hosts list. Please note that 127.0.0.1 and ::1

List of hosts to which all outgoing mail is passed to and that takes care
294
of delivering it. Multiple hosts are semicolon separated. Each of the
295
hosts is tried, in the order specified (See exim specification,
296
chapter 20.5). All deliveries go out to TCP port 25 unless a different
297
port is specified after the host name, separated from the host name by
298
two colons. Colons in IPv6 addresses need to be doubled. If a port
299
number follows, IP addresses may be enclosed in brackets, which might

be the only possibility to specify delivery to an IPv6 address and a
301
different port. Examples:
