8 | # This is a default configuration file which will operate correctly in | |
9 | # uncomplicated installations. Please see the manual for a complete list | |
10 | # of all the runtime configuration options that can be included in a | |
11 | # configuration file. There are many more than are mentioned here. The | |
12 | # manual is in the file doc/spec.txt in the Exim distribution as a plain | |
13 | # ASCII file. Other formats (PostScript, Texinfo, HTML, PDF) are available | |
14 | # from the Exim ftp sites. The manual is also online at the Exim web sites. | |
15 | ||
16 | ||
17 | # This file is divided into several parts, all but the first of which are | |
18 | # headed by a line starting with the word "begin". Only those parts that | |
19 | # are required need to be present. Blank lines, and lines starting with # | |
20 | # are ignored. | |

24 | # # | |
25 | # Whenever you change Exim's configuration file, you *must* remember to # | |
26 | # HUP the Exim daemon, because it will not pick up the new configuration # | |
27 | # until you do. However, any other Exim processes that are started, for # | |
28 | # example, a process started by an MUA in order to send a message, will # | |
29 | # see the new configuration as soon as it is in place. # | |
30 | # # | |
31 | # You do not need to HUP the daemon for changes in auxiliary files that # | |
32 | # are referenced from this file. They are read every time they are used. # | |
33 | # # | |
34 | # It is usually a good idea to test a new configuration for syntactic # | |
35 | # correctness before installing it (for example, by running the command # | |
36 | # "exim -C /config/file.new -bV"). # | |

43 | # MAIN CONFIGURATION SETTINGS # | |
44 | ###################################################################### | |
45 | ||
46 | # Specify your host's canonical name here. This should normally be the fully | |
47 | # qualified "official" name of your host. If this option is not set, the | |
48 | # uname() function is called to obtain the name. In many cases this does | |
49 | # the right thing and you need not set anything explicitly. | |
50 | ||
51 | # primary_hostname = | |
52 | ||
53 | ||
54 | # The next three settings create two lists of domains and one list of hosts. | |
55 | # These lists are referred to later in this configuration using the syntax | |
56 | # +local_domains, +relay_to_domains, and +relay_from_hosts, respectively. They | |
57 | # are all colon-separated lists: | |
58 | ||
59 | domainlist local_domains = @ | |
60 | domainlist relay_to_domains = | |
61 | hostlist relay_from_hosts = 127.0.0.1 | |
62 | ||
63 | # Most straightforward access control requirements can be obtained by | |
64 | # appropriate settings of the above options. In more complicated situations, you | |
65 | # may need to modify the Access Control List (ACL) which appears later in this | |
66 | # file. | |
67 | ||
68 | # The first setting specifies your local domains, for example: | |
69 | # | |
70 | # domainlist local_domains = my.first.domain : my.second.domain | |
71 | # | |
72 | # You can use "@" to mean "the name of the local host", as in the default | |
73 | # setting above. This is the name that is specified by primary_hostname, | |
74 | # as specified above (or defaulted). If you do not want to do any local | |
75 | # deliveries, remove the "@" from the setting above. If you want to accept mail | |
76 | # addressed to your host's literal IP address, for example, mail addressed to | |
77 | # "user@[192.168.23.44]", you can add "@[]" as an item in the local domains | |
78 | # list. You also need to uncomment "allow_domain_literals" below. This is not | |
79 | # recommended for today's Internet. | |
80 | ||
81 | # The second setting specifies domains for which your host is an incoming relay. | |
82 | # If you are not doing any relaying, you should leave the list empty. However, | |
83 | # if your host is an MX backup or gateway of some kind for some domains, you | |
84 | # must set relay_to_domains to match those domains. For example: | |
85 | # | |
86 | # domainlist relay_to_domains = *.myco.com : my.friend.org | |
87 | # | |
88 | # This will allow any host to relay through your host to those domains. | |
89 | # See the section of the manual entitled "Control of relaying" for more | |
90 | # information. | |
91 | ||
92 | # The third setting specifies hosts that can use your host as an outgoing relay | |
93 | # to any other host on the Internet. Such a setting commonly refers to a | |
94 | # complete local network as well as the localhost. For example: | |
95 | # | |
96 | # hostlist relay_from_hosts = 127.0.0.1 : 192.168.0.0/16 | |
97 | # | |
98 | # The "/16" is a bit mask (CIDR notation), not a number of hosts. Note that you | |
99 | # have to include 127.0.0.1 if you want to allow processes on your host to send | |
100 | # SMTP mail by using the loopback address. A number of MUAs use this method of | |
101 | # sending mail. | |
102 | ||
059ec3d9 PH |
103 | # All three of these lists may contain many different kinds of item, including |
104 | # wildcarded names, regular expressions, and file lookups. See the reference | |
74e0617f PH |
105 | # manual for details. The lists above are used in the access control lists for |
106 | # checking incoming messages. The names of these ACLs are defined here: | |
059ec3d9 PH |
107 | |
108 | acl_smtp_rcpt = acl_check_rcpt | |
74e0617f PH |
109 | acl_smtp_data = acl_check_data |
110 | ||
111 | # You should not change those settings until you understand how ACLs work. | |
112 | ||
113 | ||
114 | # If you are running a version of Exim that was compiled with the content- | |
115 | # scanning extension, you can cause incoming messages to be automatically | |
116 | # scanned for viruses. You have to modify the configuration in two places to | |
117 | # set this up. The first of them is here, where you define the interface to | |
118 | # your scanner. This example is typical for ClamAV; see the manual for details | |
119 | # of what to set for other virus scanners. The second modification is in the | |
120 | # acl_check_data access control list (see below). | |
059ec3d9 | 121 | |
74e0617f PH |
122 | # av_scanner = clamd:/tmp/clamd |
123 | ||
124 | ||
125 | # For spam scanning, there is a similar option that defines the interface to | |
126 | # SpamAssassin. You do not need to set this if you are using the default, which | |
127 | # is shown in this commented example. As for virus scanning, you must also | |
128 | # modify the acl_check_data access control list to enable spam scanning. | |
129 | ||
130 | # spamd_address = 127.0.0.1 783 | |
059ec3d9 PH |

133 | # Specify the domain you want to be added to all unqualified addresses | |
134 | # here. An unqualified address is one that does not contain an "@" character | |
135 | # followed by a domain. For example, "caesar@rome.example" is a fully qualified | |
136 | # address, but the string "caesar" (i.e. just a login name) is an unqualified | |
137 | # email address. Unqualified addresses are accepted only from local callers by | |
138 | # default. See the recipient_unqualified_hosts option if you want to permit | |
139 | # unqualified addresses from remote sources. If this option is not set, the | |
140 | # primary_hostname value is used for qualification. | |
141 | ||
142 | # qualify_domain = | |
143 | ||
144 | ||
145 | # If you want unqualified recipient addresses to be qualified with a different | |
146 | # domain to unqualified sender addresses, specify the recipient domain here. | |
147 | # If this option is not set, the qualify_domain value is used. | |
148 | ||
149 | # qualify_recipient = | |
150 | ||
151 | ||
152 | # The following line must be uncommented if you want Exim to recognize | |
153 | # addresses of the form "user@[10.11.12.13]" that is, with a "domain literal" | |
154 | # (an IP address) instead of a named domain. The RFCs still require this form, | |
155 | # but it makes little sense to permit mail to be sent to specific hosts by | |
156 | # their IP address in the modern Internet. This ancient format has been used | |
157 | # by those seeking to abuse hosts by using them for unwanted relaying. If you | |
158 | # really do want to support domain literals, uncomment the following line, and | |
159 | # see also the "domain_literal" router below. | |
160 | ||
161 | # allow_domain_literals | |
162 | ||
163 | ||
164 | # No deliveries will ever be run under the uids of these users (a colon- | |
165 | # separated list). An attempt to do so causes a panic error to be logged, and | |
166 | # the delivery to be deferred. This is a paranoic safety catch. There is an | |
167 | # even stronger safety catch in the form of the FIXED_NEVER_USERS setting | |
168 | # in the configuration for building Exim. The list of users that it specifies | |
169 | # is built into the binary, and cannot be changed. The option below just adds | |
170 | # additional users to the list. The default for FIXED_NEVER_USERS is "root", | |
171 | # but just to be absolutely sure, the default here is also "root". | |
172 | ||
173 | # Note that the default setting means you cannot deliver mail addressed to root | |
174 | # as if it were a normal user. This isn't usually a problem, as most sites have | |
175 | # an alias for root that redirects such mail to a human administrator. | |
176 | ||

180 | # The setting below causes Exim to do a reverse DNS lookup on all incoming | |
181 | # IP calls, in order to get the true host name. If you feel this is too | |

190 | # calls. You can limit the hosts to which these calls are made, and/or change | |
191 | # the timeout that is used. If you set the timeout to zero, all RFC 1413 calls | |
192 | # are disabled. RFC 1413 calls are cheap and can provide useful information | |
193 | # for tracing problem messages, but some hosts and firewalls have problems | |
194 | # with them. This can result in a timeout instead of an immediate refused | |
195 | # connection, leading to delays on starting up an SMTP session. | |

201 | # By default, Exim expects all envelope addresses to be fully qualified, that | |
202 | # is, they must contain both a local part and a domain. If you want to accept | |
203 | # unqualified addresses (just a local part) from certain hosts, you can specify | |
204 | # these hosts by setting one or both of | |
205 | # | |
206 | # sender_unqualified_hosts = | |
207 | # recipient_unqualified_hosts = | |

211 | # and/or qualify_recipient (see above). | |
212 | ||
213 | ||
214 | # If you want Exim to support the "percent hack" for certain domains, | |
215 | # uncomment the following line and provide a list of domains. The "percent | |
216 | # hack" is the feature by which mail addressed to x%y@z (where z is one of | |
217 | # the domains listed) is locally rerouted to x@y and sent on. If z is not one | |
218 | # of the "percent hack" domains, x%y is treated as an ordinary local part. This | |
219 | # hack is rarely needed nowadays; you should not enable it unless you are sure | |
220 | # that you really need it. | |
221 | # | |
222 | # percent_hack_domains = | |

263 | # The following section of the ACL is concerned with local parts that contain | |
264 | # @ or % or ! or / or | or dots in unusual places. | |
265 | # | |
266 | # The characters other than dots are rarely found in genuine local parts, but | |
267 | # are often tried by people looking to circumvent relaying restrictions. | |
268 | # Therefore, although they are valid in local parts, these rules lock them | |
269 | # out, as a precaution. | |
270 | # | |
271 | # Empty components (two dots in a row) are not valid in RFC 2822, but Exim | |
272 | # allows them because they have been encountered. (Consider local parts | |
273 | # constructed as "firstinitial.secondinitial.familyname" when applied to | |
274 | # someone like me, who has no second initial.) However, a local part starting | |
275 | # with a dot or containing /../ can cause trouble if it is used as part of a | |
276 | # file name (e.g. for a mailing list). This is also true for local parts that | |
277 | # contain slashes. A pipe symbol can also be troublesome if the local part is | |
278 | # incorporated unthinkingly into a shell command line. | |
279 | # | |
280 | # Two different rules are used. The first one is stricter, and is applied to | |
281 | # messages that are addressed to one of the local domains handled by this | |
282 | # host. It blocks local parts that begin with a dot or contain @ % ! / or |. | |

291 | # allows your own users to send outgoing messages to sites that use slashes | |
292 | # and vertical bars in their local parts. It blocks local parts that begin | |
293 | # with a dot, slash, or vertical bar, but allows these characters within the | |
294 | # local part. However, the sequence /../ is barred. The use of @ % and ! is | |

457 | # If you install this configuration by hand, you need to specify the correct | |
458 | # path in the "data" setting below. | |
459 | # | |
460 | ##### NB You must ensure that the alias file exists. It used to be the case | |

468 | # as appropriate) and adding a "group" option if necessary. Alternatively, you | |
469 | # can specify "user" on the transports that are used. Note that the transports | |
