Hi zusammen,

ich habe momentan ein Problem, unzwar habe ich meinen E-mail Server nach diesem Howto eingerichtet. Das Problem von Anfang an war, dass ich mit Debian Etch kein postfix-tls installieren konnte. Erstens wirds mit apt-get nicht gefunden und wenn ich es hiermit manuell installieren will, kommt diese Meldung.
Code:
Wähle vormals abgewähltes Paket postfix-tls.
dpkg: Betreffend postfix-tls_2.1.5-9_i386.deb, welches postfix-tls enthält:
 postfix kollidiert mit postfix-tls
  postfix-tls (Version 2.1.5-9) soll installiert werden.
dpkg: Fehler beim Bearbeiten von postfix-tls_2.1.5-9_i386.deb (--install):
 Kollidierende Pakete - installiere postfix-tls nicht
Fehler traten auf beim Bearbeiten von:
 postfix-tls_2.1.5-9_i386.deb
Ich habe dann erstmal mit dem Howto weitergemacht. Und habe nun diese Postfix main.cf

## Mailbox locations and namespaces
##

# Location for users' mailboxes. This is the same as the old default_mail_env
# setting. The default is empty, which means that Dovecot tries to find the
# mailboxes automatically. This won't work if the user doesn't have any mail
# yet, so you should explicitly tell Dovecot the full location.
#
# If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u)
# isn't enough. You'll also need to tell Dovecot where the other mailboxes are
# and where Dovecot can place its index files. This is called the "root mail
# directory", and it must be the first path given in the mail_location setting.
#
# There are a few special variables you can use, eg.:
#
#   %u - username
#   %n - user part in user@domain, same as %u if there's no domain
#   %d - domain part in user@domain, empty if there's no domain
#   %h - home directory
#
# See /usr/share/doc/dovecot-common/variables.txt for full list. Some examples:
#
#   mail_location = maildir:~/Maildir
#   mail_location = mbox:~/mail:INBOX=/var/mail/%u
#   mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n
#
# http://wiki.dovecot.org/MailLocation
#
#mail_location = maildir:%h/mails

# If you need to set multiple mailbox locations or want to change default
# namespace settings, you can do it by defining namespace sections:
#
# You can have private, shared and public namespaces. The only difference
# between them is how Dovecot announces them to client via NAMESPACE
# extension. Shared namespaces are meant for user-owned mailboxes which are
# shared to other users, while public namespaces are for more globally
# accessible mailboxes.
#
# REMEMBER: If you add any namespaces, the default namespace must be added
# explicitly, ie. mail_location does nothing unless you have a namespace
# without a location setting. Default namespace is simply done by having a
# namespace with empty prefix.
#namespace private {
   # Hierarchy separator to use. You should use the same separator for all
   # namespaces or some clients get confused. '/' is usually a good one.
   # The default however depends on the underlying mail storage format.
   #separator = 

   # Prefix required to access this namespace. This needs to be different for
   # all namespaces. For example "Public/".
   #prefix = 

   # Physical location of the mailbox. This is in same format as
   # mail_location, which is also the default for it.
   #location =

   # There can be only one INBOX, and this setting defines which namespace
   # has it.
   #inbox = yes

   # If namespace is hidden, it's not advertised to clients via NAMESPACE
   # extension or shown in LIST replies. This is mostly useful when converting
   # from another server with different namespaces which you want to depricate
   # but still keep working. For example you can create hidden namespaces with
   # prefixes "~/mail/", "~%u/mail/" and "mail/".
   #hidden = yes
#}

# Grant access to these extra groups for mail processes. Typical use would be
# to give "mail" group write access to /var/mail to be able to create dotlocks.

# ones; the list of groups must be separated by spaces.

## Mailbox handling optimizations
##

# Space-separated list of fields to initially save into cache file. Currently
# these fields are allowed:
#
#  flags, date.sent, date.received, size.virtual, size.physical
#  mime.parts, imap.body, imap.bodystructure
#
# Different IMAP clients work in different ways, so they benefit from
# different cached fields. Some do not benefit from them at all. Caching more
# than necessary generates useless disk I/O, so you don't want to do that
# either.
#
# Dovecot attempts to automatically figure out what client wants and it keeps
# only that. However the first few times a mailbox is opened, Dovecot hasn't
# yet figured out what client needs, so it may not perform optimally. If you
# know what fields the majority of your clients need, it may be useful to set
# these fields by hand. If client doesn't actually use them, Dovecot will
# eventually drop them.
#
# Usually you should just leave this field alone. The potential benefits are
# typically unnoticeable.
#mail_cache_fields = 

# Space-separated list of fields that Dovecot should never save to cache file.
# Useful if you want to save disk space at the cost of more I/O when the fields
# needed.
#mail_never_cache_fields =

# file. This allows optimizing Dovecot's behavior to do less disk writes at
# the cost of more disk reads.

# When IDLE command is running, mailbox is checked once in a while to see if
# there are any new mails or other changes. This setting defines the minimum
# time to wait between those checks. Dovecot is however able to use dnotify
# and inotify with Linux to reply immediately after the change occurs.
#mailbox_idle_check_interval = 30

# Save mails with CR+LF instead of plain LF. This makes sending those mails
# take less CPU, especially with sendfile() syscall with Linux and FreeBSD.
# But it also creates a bit more disk I/O which may just make it slower.
# Also note that if other software reads the mboxes/maildirs, they may handle
# the extra CRs wrong and cause problems.
#mail_save_crlf = no

##
## Maildir-specific settings
##

# By default LIST command returns all entries in maildir beginning with dot.
# Enabling this option makes Dovecot return only entries which are directories.

# done always regardless of this setting)
#maildir_stat_dirs = no

# Copy mail to another folders using hard links. This is much faster than
# actually copying the file. This is problematic only if something modifies
# the mail in one folder but doesn't want it modified in the others. I don't

# requires that the mails don't change, so it would be problematic in any case.
# If you care about performance, enable it.
#maildir_copy_with_hardlinks = no

##
## mbox-specific settings

#           will need write access to that directory.
#  fcntl  : Use this if possible. Works with NFS too if lockd is used.
#  flock  : May not exist in all systems. Doesn't work with NFS.
#  lockf  : May not exist in all systems. Doesn't work with NFS.
#
# You can use multiple locking methods; if you do the order they're declared
# in is important to avoid deadlocks if other MTAs/MUAs are using multiple
# locking methods as well. Some operating systems don't allow using some of
# them simultaneously.

# When mbox changes unexpectedly we have to fully read it to find out what
# changed. If the mbox is large this can take a long time. Since the change
# is usually just a newly appended mail, it'd be faster to simply read the
# new mails. If this setting is enabled, Dovecot does this but still safely
# fallbacks to re-reading the whole mbox file whenever something in mbox isn't
# how it's expected to be. The only real downside to this setting is that if
# some other MUA changes message flags, Dovecot doesn't notice it immediately.

  # Password database is used to verify user's password (and nothing more).

  # duplicating the system users into virtual database.

  #
  # By adding master=yes setting inside a passdb you make the passdb a list
  # of "master users", who can log in as anyone else. Unless you're using PAM,
  # you probably still want the destination user to be looked up from passdb
  # that it really exists. This can be done by adding pass=yes setting to the
  # master passdb.
  #
  # http://wiki.dovecot.org/MasterPassword

  # Users can be temporarily disabled by adding a passdb with deny=yes.
  # If the user is found from that database, authentication will fail.
  # The deny passdb should always be specified before others, so it gets
  # checked first. Here's an example:

  #passdb passwd-file {
    # File contains a list of usernames, one per line
    #args = /etc/dovecot.deny

  # Note that PAM can only be used to verify if user's password is correct,

  # authentication to actually work.

## Dictionary server settings

# Dictionary can be used by some plugins to store key=value lists.
# Currently this is only used by dict quota backend. The dictionary can be
# used either directly or though a dictionary server. The following dict block
# maps dictionary names to URIs when the server is used. These can then be
# referenced using URIs in format "proxy:<name>".

dict {
  #quota = mysql:/etc/dovecot-dict-quota.conf

## Plugin settings
##

plugin {
  # Here you can give some extra environment variables to mail processes.
  # This is mostly meant for passing parameters to plugins. %variable
  # expansion is done for all values.

  # Quota plugin. Multiple backends are supported:
  #   dirsize: Find and sum all the files found from mail directory
  #   dict: Keep quota stored in dictionary (eg. SQL)
  #   maildir: Maildir++ quota
  #   fs: Read-only support for filesystem quota
  #quota = maildir

  # ACL plugin. vfile backend reads ACLs from "dovecot-acl" file from maildir
  # directory. You can also optionally give a global ACL directory path where
  # ACLs are applied to all users' mailboxes. The global ACL directory contains
  # one file for each mailbox, eg. INBOX or sub.mailbox.
  #acl = vfile:/etc/dovecot-acls

  # Convert plugin. If set, specifies the source storage path which is
  # converted to destination storage (mail_location).
  #convert_mail = mbox:%h/mail

  # Trash plugin. When saving a message would make user go over quota, this
  # plugin automatically deletes the oldest mails from configured mailboxes
  # until the message can be saved within quota limits. The configuration file
  # is a text file where each line is in format: <priority> <mailbox name>
  # Mails are first deleted in lowest -> highest priority number order
  #trash = /etc/dovecot-trash.conf

Ichkann nun mit einem Zertifikat von meinem Server E-mails abholen, mit Evolution. Leider kann ich mit Evolution keine E-mails über meinen Mailserver verschicken. Als Meldung bekomme ich ein Timeout.

Liegt das nun an tls, weil ich es nicht installieren konnte oder liegt der Fehler woanders? Wie kann ich das Problem lösen?
