Ik heb op mijn debian wheezy bak exim4 draaien voor mijn smtp gebeuren. Samen met dovecot en fetchmail wil ik dit inrichten als IMAP mailserver. Lekker handig zodat de hele fam. op een PC/tablet of telefoon bij zijn mail kan.

Intern heb ik de boel aan het werk. Kan via verschillende mail clients bij de server en kan intern verschillende gebruikers mailen.

Nu krijg ik het alleen nog niet voor elkaar om (via exim4) met mijn domain naar buiten te mailen.

Via dds.nl hebben we met de familie een domain (in mijn voorbeeld FAMILIE.nl). De smtp server van dds is smtp.dds.nl op poort 25/26/587. Mijn client machine jetfine.lan en mijn mailserver jazz.lan

Hieronder een log van als ik van client jetfire met thunderbird een mailtje stuur naar user AAAAA. Geen problemen mail komt perfect over.

Heeft iemand wat aanknopingspunten voor mij?

Hieronder mijn volledige exim4 config. Alvast sorry!! Ik kon niet vinden hoe ik een bloktekst als code handig kon weergeven zodat je het kon openklappen.

  # The following section of the ACL is concerned with local parts that contain
  # certain non-alphanumeric characters. Dots in unusual places are
  # handled by this ACL as well.
  #
  # Non-alphanumeric characters other than dots are rarely found in genuine
  # local parts, but are often tried by people looking to circumvent
  # relaying restrictions. Therefore, although they are valid in local
  # parts, these rules disallow certain non-alphanumeric characters, as
  # a precaution.
  #
  # Empty components (two dots in a row) are not valid in RFC 2822, but Exim
  # allows them because they have been encountered. (Consider local parts
  # constructed as "firstinitial.secondinitial.familyname" when applied to
  # a name without a second initial.) However, a local part starting
  # with a dot or containing /../ can cause trouble if it is used as part of a
  # file name (e.g. for a mailing list). This is also true for local parts that
  # contain slashes. A pipe symbol can also be troublesome if the local part is
  # incorporated unthinkingly into a shell command line.
  #
  # These ACL components will block recipient addresses that are valid

  # checking, please feel free to change the default values of the macros
  # defined in main/01_exim4-config_listmacrosdefs or override them from a
  # local configuration file.
  # 
  # Two different rules are used. The first one has a quite strict
  # default, and is applied to messages that are addressed to one of the
  # local domains handled by this host.

  # The default value of CHECK_RCPT_LOCAL_LOCALPARTS is defined in
  # main/01_exim4-config_listmacrosdefs:
  # CHECK_RCPT_LOCAL_LOCALPARTS = ^[.] : ^.*[@%!/|`#&?]
  # This blocks local parts that begin with a dot or contain a quite
  # broad range of non-alphanumeric characters.

  # main/01_exim4-config_listmacrosdefs:
  # CHECK_RCPT_REMOTE_LOCALPARTS = ^[./|] : ^.*[@%!`#&?] : ^.*/\\.\\./

  # It allows local 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 some other non-alphanumeric characters is blocked.
  # Single quotes might probably be dangerous as well, but they're

# This router handles forwarding using traditional .forward files in users'
# home directories. It also allows mail filtering with a forward file
# starting with the string "# Exim filter" or "# Sieve filter".
#
# The no_verify setting means that this router is skipped when Exim is
# verifying addresses. Similarly, no_expn means that this router is skipped if
# Exim is processing an EXPN command.
#
# The check_ancestor option means that if the forward file generates an
# address that is an ancestor of the current one, the current one gets
# passed on instead. This covers the case where A is aliased to B and B
# has a .forward file pointing to A.
#
# The four transports specified at the end are those that are used when
# forwarding generates a direct delivery to a directory, or a file, or to a
# pipe, or sets up an auto-reply, respectively.

#################################

# The examples below are for server side authentication, when the
# local exim is SMTP server and clients authenticate to the local exim.

# They allow two styles of plain-text authentication against an
# CONFDIR/passwd file whose syntax is described in exim4_passwd(5).

# Hosts that are allowed to use AUTH are defined by the
# auth_advertise_hosts option in the main configuration. The default is
# "*", which allows authentication to all hosts over all kinds of
# connections if there is at least one authenticator defined here.
# Authenticators which rely on unencrypted clear text passwords don't
# advertise on unencrypted connections by default. Thus, it might be
# wise to set up TLS to allow encrypted connections. If TLS cannot be
# used for some reason, you can set AUTH_SERVER_ALLOW_NOTLS_PASSWORDS to
# advertise unencrypted clear text password based authenticators on all
# connections. As this is severely reducing security, using TLS is
# preferred over allowing clear text password based authenticators on
# unencrypted connections.

# 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_server:
#   driver = plaintext
#   public_name = PLAIN
#   server_condition = "${if crypteq{$auth3}{${extract{1}{:}{${lookup{$auth2}lsearch{CONFDIR/passwd}{$value}{*:*}}}}}{1}{0}}"

#   server_prompts = :
#   .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS
#   server_advertise_condition = ${if eq{$tls_cipher}{}{}{*}}
#   .endif

# 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.

# login_server:

# This one is a bad hack to support the broken version 4.xx of

# If your list of offered authenticators is other than PLAIN and LOGIN,
# you need to adapt the public_name line manually.
# It has to be the last authenticator to work and has not been tested
# well. Use at your own risk.

Heb net "update-exim4.conf.conf" aangepast.

dc_smarthost='smtp.dds.nl::587'

vervangen door

dc_smarthost='smtp.ziggo.nl'

Nu werkt net. Ik begrijk alleen totaal niet waarom de AUTH PLAIN login niet goed krijg.

Iemand ideeën?

Hoe dan ook moet je smarthost niet met 2x dubbele punt.

Duct tape can't fix stupid, but it can muffle the sound.

Je realiseert je dat de <user@domain> in passwd.client de gegevens zijn waarmee ingelogd wordt? Die hebben niks te maken met het adres waar je naartoe stuurt.

Volgens het voorbeeld in http://www.dds.nl/helpdesk/cat.php?cat=mail&id=14 moet je zonder domein inloggen.

Maar, waarom wil je niet gewoon via ziggo sturen? Dat is het idee van een smarthost namelijk.

Die hele config posten was trouwens ook bepaald niet nodig. Ten eerste irrelevant, en belangrijker 't is de standaard debian templated config; die kunnen we zelf ook wel vinden
