Známý šifrovaný komunikátor Signal od verze 3.30.0 již nevyžaduje Google Play Services. Autoři tak po letech vyslyšeli volání komunity, která dala vzniknout Google-free forku LibreSignal (dnes již neudržovaný). Oficiální binárky jsou stále distribuované pouze přes Google Play, ale lze použít neoficiální F-Droid repozitář fdroid.eutopia.cz s nezávislými buildy Signalu nebo oficiální binárku stáhnout z Google Play i bez Google účtu

    Exim 4.69 - změněná adresa odesílatele
    Přečteno: 1429×
    Ahoj. Mám problém s mailovým systémem Exim. Mám vytvořený účet řekněme honza@firma.cz. Pokud z tohoto účtu pošlu mail tak se pošle jako honza@firma.cz@firma.cz (to je v hlavičce) což je špatně a některé mailservery tento mail odmítnou. Nevítě někdo co s tím? Kde co nastavit? Prošel jsem celý konfigurák a nevím si rady :(. Zde chyba z logu:
    2008-04-26 22:25:03 1Jpqwy-0005DQ-Eg <= "honza@firma.cz"@firma.cz H=r19bc185.net.upc.cz (MujPC) [77.101.54.185] P=esmtpa A=login:honza@firma.cz S=1449 id=076D62FBD76E4DA4881C1BB585D5C678@VistaPC

    # Whenever you change Exim's configuration file, you *must* remember to    #
    # HUP the Exim daemon, because it will not pick up the new configuration   #
    # until you do. However, any other Exim processes that are started, for    #
    # example, a process started by an MUA in order to send a message, will    #
    # see the new configuration as soon as it is in place.                     #

    # qualified "official" name of your host. If this option is not set, the
    # uname() function is called to obtain the name. In many cases this does
    # the right thing and you need not set anything explicitly.
    
    primary_hostname = mail.perfect-system.cz
    
    # The next three settings create two lists of domains and one list of hosts.
    # These lists are referred to later in this configuration using the syntax
    # +local_domains, +relay_to_domains, and +relay_from_hosts, respectively. They
    # are all colon-separated lists:
    
    domainlist local_domains = ${lookup pgsql {SELECT is_local_domain('${domain}') }}

    hostlist   relay_from_hosts = 127.0.0.1 : 192.168.1.0/24
    
    # Most straightforward access control requirements can be obtained by
    # appropriate settings of the above options. In more complicated situations,
    # you may need to modify the Access Control Lists (ACLs) which appear later in
    # this file.
    
    # The first setting specifies your local domains, for example:
    #
    #   domainlist local_domains = my.first.domain : my.second.domain
    #
    # You can use "@" to mean "the name of the local host", as in the default
    # setting above. This is the name that is specified by primary_hostname,
    # as specified above (or defaulted). If you do not want to do any local
    # deliveries, remove the "@" from the setting above. If you want to accept mail
    # addressed to your host's literal IP address, for example, mail addressed to
    # you can add "@[]" as an item in the local domains
    # list. You also need to uncomment "allow_domain_literals" below. This is not
    # recommended for today's Internet.
    
    # The second setting specifies domains for which your host is an incoming relay.
    # If you are not doing any relaying, you should leave the list empty. However,
    # if your host is an MX backup or gateway of some kind for some domains, you
    # must set relay_to_domains to match those domains. For example:
    #
    # domainlist relay_to_domains = *.myco.com : my.friend.org
    #
    # This will allow any host to relay through your host to those domains.
    # See the section of the manual entitled "Control of relaying" for more
    # information.
    
    # The third setting specifies hosts that can use your host as an outgoing relay
    # to any other host on the Internet. Such a setting commonly refers to a
    # complete local network as well as the localhost. For example:
    #
    # hostlist relay_from_hosts = 127.0.0.1 : 192.168.0.0/16
    #
    # The "/16" is a bit mask (CIDR notation), not a number of hosts. Note that you
    # have to include 127.0.0.1 if you want to allow processes on your host to send
    # SMTP mail by using the loopback address. A number of MUAs use this method of
    # sending mail.
    
    # All three of these lists may contain many different kinds of item, including
    # wildcarded names, regular expressions, and file lookups. See the reference
    # manual for details. The lists above are used in the access control lists for
    # checking incoming messages. The names of these ACLs are defined here:

    acl_smtp_data = acl_check_data
    
    # You should not change those settings until you understand how ACLs work.
    
    
    # If you are running a version of Exim that was compiled with the content-
    # scanning extension, you can cause incoming messages to be automatically
    # scanned for viruses. You have to modify the configuration in two places to
    # set this up. The first of them is here, where you define the interface to
    # your scanner. This example is typical for ClamAV; see the manual for details
    # of what to set for other virus scanners. The second modification is in the
    # acl_check_data access control list (see below).
    
    av_scanner = clamd:/var/run/clamav/clamd.sock
    
    
    # For spam scanning, there is a similar option that defines the interface to
    # SpamAssassin. You do not need to set this if you are using the default, which
    # is shown in this commented example. As for virus scanning, you must also
    # modify the acl_check_data access control list to enable spam scanning.
    
    spamd_address = 127.0.0.1 783
    
    
    # If Exim is compiled with support for TLS, you may want to enable the
    # following options so that Exim allows clients to make encrypted
    # connections. In the authenticators section below, there are template
    # configurations for plaintext username/password authentication. This kind
    # of authentication is only safe when used within a TLS connection, so the
    # authenticators will only work if the following TLS settings are turned on

    # options.

    # tls_privatekey = /etc/ssl/exim.pem
    
    # In order to support roaming users who wish to send email from anywhere,
    # you may want to make Exim listen on other ports as well as port 25, in
    # case these users need to send email from a network that blocks port 25.
    # The standard port for this purpose is port 587, the "message submission"
    # port. See RFC 4409 for details. Microsoft MUAs cannot be configured to
    # talk the message submission protocol correctly, so if you need to support
    # them you should also allow TLS-on-connect on the traditional but
    # non-standard port 465.

    # here. An unqualified address is one that does not contain an "@" character
    # followed by a domain. For example, "caesar@rome.example" is a fully qualified
    # address, but the string "caesar" (i.e. just a login name) is an unqualified
    # email address. Unqualified addresses are accepted only from local callers by
    # default. See the recipient_unqualified_hosts option if you want to permit
    # unqualified addresses from remote sources. If this option is not set, the
    # primary_hostname value is used for qualification.

    # addresses of the form that is, with a "domain literal"
    # (an IP address) instead of a named domain. The RFCs still require this form,
    # but it makes little sense to permit mail to be sent to specific hosts by
    # their IP address in the modern Internet. This ancient format has been used
    # by those seeking to abuse hosts by using them for unwanted relaying. If you

    # No deliveries will ever be run under the uids of users specified by
    # never_users (a colon-separated list). An attempt to do so causes a panic
    # error to be logged, and the delivery to be deferred. This is a paranoic
    # safety catch. There is an even stronger safety catch in the form of the
    # FIXED_NEVER_USERS setting in the configuration for building Exim. The list of
    # users that it specifies is built into the binary, and cannot be changed. The
    # option below just adds additional users to the list. The default for
    # FIXED_NEVER_USERS is "root", but just to be absolutely sure, the default here
    # is also "root".

    # the timeout that is used. If you set the timeout to zero, all RFC 1413 calls
    # are disabled. RFC 1413 calls are cheap and can provide useful information
    # for tracing problem messages, but some hosts and firewalls have problems
    # with them. This can result in a timeout instead of an immediate refused

    # the domains listed) is locally rerouted to x@y and sent on. If z is not one
    # of the "percent hack" domains, x%y is treated as an ordinary local part. This

    # system degrades with many files in one directory, this is less likely to

      # defined by the "domainlist local_domains" setting above. The rule  blocks
      # local parts that begin with a dot or contain @ % ! / or |. If you have

      # "domains = !+local_domains" restricts it to domains that are NOT defined by
      # the "domainlist local_domains" setting above. The exclamation mark is a
      # negating operator. This rule allows your own users to send outgoing
      # messages to sites that use slashes and vertical bars in their local parts.
      # It blocks local parts that begin with a dot, slash, or vertical bar, but
      # allows these characters within the local part. However, the sequence /../
      # is barred. The use of @ % and ! is blocked, as before. The motivation here

    # . The RFCs require this facility. However, it is
    # little-known these days, and has been exploited by evil people seeking
    # to abuse SMTP relays. Consequently it is commented out in the default
    # configuration. If you uncomment this router, you also need to uncomment
    # allow_domain_literals above, so that Exim can recognize the syntax of
    # domain literal addresses.

    # This router routes addresses that are not in local domains by doing a DNS
    # lookup on the domain name. The exclamation mark that appears in "domains = !
    # +local_domains" is a negating operator, that is, it can be read as "not". The
    # recipient's domain must not be one of those defined by "domainlist
    # local_domains" above for this router to be used.
    #
    # If the router is used, any domain that resolves to 0.0.0.0 or to a loopback
    # interface address (127.0.0.0/8) is treated as if it had no DNS entry. Note
    # that 0.0.0.0 is the same as 0.0.0.0/32, which is commonly treated as the
    # local host inside the network stack. It is not 0.0.0.0/0, the default route.
    # If the DNS lookup fails, no further routers are tried because of the no_more
    # setting, and consequently the address is unrouteable.

    # domains that are defined by "domainlist local_domains" above.
    
    
    # This router handles aliasing using a linearly searched alias file with the
    # name /etc/mail/aliases. When this configuration is installed automatically,
    # the name gets inserted into this file from whatever is set in Exim's
    # build-time configuration. The default path is the traditional /etc/aliases.
    # If you install this configuration by hand, you need to specify the correct
    # path in the "data" setting below.
    #
    ##### NB  You must ensure that the alias file exists. It used to be the case
    ##### NB  that every Unix had that file, because it was the Sendmail default.
    ##### NB  These days, there are systems that don't have it. Your aliases
    ##### NB  file should at least contain an alias for "postmaster".
    #
    # If any of your aliases expand to pipes or files, you will need to set
    # up a user and a group for these deliveries to run under. You can do
    # this by uncommenting the "user" option below (changing the user name
    # as appropriate) and adding a "group" option if necessary. Alternatively, you
    # can specify "user" on the transports that are used. Note that the transports
    # listed below are the same as are used for .forward files; you might want
    # to set up different ones for pipe and file deliveries from aliases.

    # The following authenticators support plaintext username/password
    # authentication using the standard PLAIN mechanism and the traditional
    # but non-standard LOGIN mechanism, with Exim acting as the server.
    # PLAIN and LOGIN are enough to support most MUA software.
    #
    # These authenticators are not complete: you need to change the
    # server_condition settings to specify how passwords are verified.
    # They are set up to offer authentication to the client only if the
    # connection is encrypted with TLS, so you also need to add support
    # for TLS. See the global configuration options section at the start
    # of this file for more about TLS.
    #
    # The default RCPT ACL checks for successful authentication, and will accept
    # messages from authenticated users from anywhere on the Internet.
    
    begin authenticators
    
    # PLAIN authentication has no server prompts. The client sends its
    # credentials in one lump, containing an authorization ID (which we do not
    # use), an authentication ID, and a password. The latter two appear as
    # $auth2 and $auth3 in the configuration and should be checked against a
    # valid username and password. In a real configuration you would typically
    # use $auth2 as a lookup key, and compare $auth3 against the result of the
    # lookup, perhaps using the crypteq{}{} condition.
    
    #PLAIN:
    #  driver                     = plaintext
    #  server_set_id              = $auth2
    #  server_prompts             = :
    #  server_condition           = Authentication is not yet configured
    #  server_advertise_condition = ${if def:tls_cipher }
    
    # LOGIN authentication has traditional prompts and responses. There is no
    # authorization ID in this mechanism, so unlike PLAIN the username and
    # password are $auth1 and $auth2. Apart from that you can use the same
    # server_condition setting for both authenticators.

    A dela to opravdu exim a ne postovni klient ? si prepni exim do debug modu a podivej se co dela krok za krokem. (pripadne tusim -brw je primo pro testovani address rewritingu - viz man exim)

    A jeste si omrkni casti, kde pouzivas driver redirect + data= ... tam dochazi k prepisovani adresy - takze divoky SELECT ?

    Díky moc za nakopnutí! Pustil jsem debug mode:
    19:43:51 20459   "mail@perfect-system.cz" from env-from rewritten as ""mail@perfect-system.cz"@mail.perfect-system.cz" by submission mode
    Chyba byla v parametru:
    accept  hosts         = +relay_from_hosts
    control       = submission
    Přepsal jsem na:
    accept  hosts         = +relay_from_hosts
    control       = submission/sender_retain
    Třeba to někomu v budoucnu pomůže :). Díky!
