Cyrus IMAP21 und KMail
Hallo!
Ich habe versucht mir Cyrus IMAP21 einzurichten und stehe leider etwas an. :-(
Was bisher geschah:
===================
1.) Cyrus IMAP21 installieren
1a.) cyrus21-admin
1b.) cyrus21-clients
1c.) cyrus21-common
1d.) cyrus21-doc
1e.) cyrus21-imapd
1f.) cyrus21-pop3d
2.) Gemäß "/usr/share/doc/cyrus21-imapd/README.Debian.simpleinstall.gz"
vorgehen
2a.) Überprüft ob "libsasl2-modules", "libsasl2" und "sasl2-bin" installiert
sind.
=> dpkg-query -s <Paketname>
2b.) Sichergestellt, dass "/etc/sasldb2" von der Gruppe "sasl" gelesen werden
kann.
=> ls -l /etc/sasldb2
=> -rw-rw---- 1 root sasl 49152 Sep 13 21:46 /etc/sasldb2
2c.) Sichergestellt, dass der Benutzer "cyrus" zur Gruppe "sasl" gehört.
=> view /etc/group
=> sasl:x:45:cyrus
2d.) "/etc/cyrus.conf" editieren und sicherstellen, dass die erforderlichen
Dienste (services) eingeschaltet sind.
=> Auszug aus "/etc/cyrus.conf":
# UNIX sockets start with a slash and are absolute paths
# you can use a maxchild=# to limit the maximum number of forks of a service
# you can use babysit=true and maxforkrate=# to keep tight tabs on the service
# most services also accept -U (limit number of reuses) and -T (timeout)
SERVICES {
# --- Normal cyrus spool, or Murder backends ---
# add or remove based on preferences
imap cmd="imapd -U 30" listen="imap" prefork=0 maxchild=100
#imaps cmd="imapd -s -U 30" listen="imaps" prefork=0 maxchild=100
pop3 cmd="pop3d -U 30" listen="pop3" prefork=0 maxchild=50
#pop3s cmd="pop3d -s -U 30" listen="pop3s" prefork=0 maxchild=50
# At least one form of LMTP is required for delivery
# (you must keep the Unix socket name in sync with imap.conf)
#lmtp cmd="lmtpd" listen="localhost:lmtp" prefork=0 maxchild=20
lmtpunix cmd="lmtpd" listen="/var/run/cyrus/socket/lmtp" prefork=0
maxchild=20
# ----------------------------------------------
}
2e.) Die Datei "/etc/imapd.conf" editieren und sicherstellen, dass man einige
"admin" Benutzer unter dem Eintrag "admins:" eingetragen hat.
=> Als Anhang beigefügt.
2f.) "saslpasswd2 -c cyrus" verwendet um einen Administrator Zugang zu
erstellen.
2g.) Mit "sasldblistusers2" Schritt "sf" überprüft.
2h.) Mit "saslpasswd2 -c" die Benutzer "leo" und "lukas" erzeugt.
2i.) Mit "cyradm --user cyrus localhost" angemeldet und mit "cm user.leo" bzw.
"cm user.lukas" zwei Mailboxen erzeugt.
2j.) Versucht als Benutzer "leo" mit "imtest" auf "localhost" anmelden.
=> imtest -u leo localhost
=> Erfolgreich
3.) Konfiguration von KMail:
3a.) Einstellungen -> KMail einrichten -> Netzwerk -> Empfang -> Hinzufügen
3b.) Allgemein
=> Benutzer: leo
=> Passwort: ***
=> Server: localhost
=> Port: 993
3c.) Sicherheit -> Fähigkeiten des Servers testen
=> Verschlüsselung = SSL für sicheres holen von Nachrichten benutzen
=> Anmelde-Methode = Einfacher Text
Poblem:
=======
Beim Versuch unter KMail auf den IMAP Ordner zuzugreifen bekomme ich die
Fehlermeldung "Keine Verbindung zu Rechner localhost".
Hier stehe ich nun an.
Fragen:
=======
* Ist das Problem eher bei KMail oder bei Cyrus IMAP zu suchen?
* Muss auch der SMTP-Server bereits konfiguriert sein, damit man IMAP
Postfächer nutzen kann?
* Müssen die händisch erstellten Postfächer spezifische Berechtigungen
aufweisen um eine Anmeldung durch KMail zuzulassen?
* Kann mir jemand mit guten Tipps helfen?
Bin wieder für jede Unterstützung dankbar.
LG,
Leonhard.
# Debian Cyrus imapd.conf
# See imapd.conf(5) for more information and more options
# Configuration directory
configdirectory: /var/lib/cyrus
# Which partition to use for default mailboxes
defaultpartition: default
partition-default: /var/spool/cyrus/mail
# News setup
partition-news: /var/spool/cyrus/news
newsspool: /var/spool/news
# Alternate namespace
# If enabled, activate the alternate namespace as documented in
# /usr/share/doc/cyrus21-doc/html/altnamespace.html, where an user's
# subfolders are in the same level as the INBOX
# See also userprefix and sharedprefix on imapd.conf(5)
altnamespace: no
# UNIX Hierarchy Convention
# Set to yes, and cyrus will accept dots in names, and use the forward
# slash "/" to delimit levels of the hierarchy. This is done by converting
# internally all dots to "^", and all "/" to dots. So the "rabbit.holes"
# mailbox of user "helmer.fudd" is stored in "user.elmer^fud.rabbit^holes"
unixhierarchysep: no
# Munging illegal characters in headers
# Headers of RFC2882 messages must not have characters with the 8th bit
# set. However, too many badly-written MUAs generate this, including most
# spamware. Disable this if you want Cyrus to leave the crappage untouched
# and you don't care that IMAP SEARCH won't work right anymore.
#munge8bit: no
# Forcing recipient user to lowercase
# Cyrus 2.1 is case-sensitive. If all your mail users are in lowercase, it is
# probably a very good idea to set lmtp_downcase_rcpt to true. The default is
# to assume the user knows what he is doing, and not downcase anything.
#lmtp_downcase_rcpt: yes
# Uncomment the following and add the space-separated users who
# have admin rights for all services.

# Space-separated list of users that have lmtp "admin" status (i.e. that
# can deliver email through TCP/IP lmtp) in addition to those in the
# admins: entry above
#lmtp_admins: postman
# Space-separated list of users that have mupdate "admin" status, in
# addition to those in the admins: entry above. Note that mupdate slaves and
# backends in a Murder cluster need to autenticate against the mupdate master
# as admin users.

# Sendmail binary location
# DUE TO A BUG, Cyrus sends CRLF EOLs to this program. This breaks Exim 3.

allowplaintext: yes
# Force PLAIN/LOGIN authentication only

# sasl_minimum_layer and allowapop below, too.
#sasl_mech_list: PLAIN
# Allow use of the POP3 APOP authentication command.

# Do note that, since sasl will be run as user cyrus, you may have a lot of
# trouble to set this up right.
sasl_pwcheck_method: auxprop
# What auxpropd plugins to load, if using sasl_pwcheck_method: auxprop
# by default, all plugins are tried (which is probably NOT what you want).
