| + | * '''2011-06-08''' I ''think'' the only change to this file was to change '''auth default { socket listen { client { path=''' from "/var/spool/postfix/private/auth" to "/var/spool/postfix/private/dovecot-auth". Finally receiving Gmails, and no known errors. I also made these changes in [[../auth.d/01-dovecot-postfix.auth]], but it wasn't until I made them here that things started working. | ||

| − | + | ## Dovecot configuration file | |
| + | |||
| + | # If you're in a hurry, see http://wiki.dovecot.org/QuickConfiguration | ||
| + | |||
| + | # "dovecot -n" command gives a clean output of the changed settings. Use it | ||
| + | # instead of copy&pasting this file when posting to the Dovecot mailing list. | ||
| + | |||
| + | # '#' character and everything after it is treated as comments. Extra spaces | ||
| + | # and tabs are ignored. If you want to use either of these explicitly, put the | ||
| + | # value inside quotes, eg.: key = "# char and trailing whitespace " | ||
| + | |||
| + | # Default values are shown for each setting, it's not required to uncomment | ||
| + | # any of the lines. Exception to this are paths, they're just examples with | ||
| + | # the real defaults being based on configure options. The paths listed here | ||
| + | # are for configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var | ||

| + | # IP or host address where to listen in for connections. It's not currently | ||
| + | # possible to specify multiple addresses. "*" listens in all IPv4 interfaces. | ||
| + | # "[::]" listens in all IPv6 interfaces, but may also listen in all IPv4 | ||
| + | # interfaces depending on the operating system. | ||
| + | # | ||
| + | # If you want to specify ports for each service, you will need to configure | ||
| + | # these settings inside the protocol imap/pop3 { ... } section, so you can | ||
| + | # specify different ports for IMAP/POP3. For example: | ||
| + | # protocol imap { | ||
| + | # listen = *:10143 | ||
| + | # ssl_listen = *:10943 | ||
| + | # .. | ||
| + | # } | ||

| + | # Disable LOGIN command and all other plaintext authentications unless | ||

| + | ## 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 | ||
| + | # kept. 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/wiki/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 | ||
| + | # | ||
| + | # <doc/wiki/MailLocation.txt> | ||
| + | # | ||
| + | mail_location = maildir:/home/vmail/%d/%u | ||
| + | |||
| + | # If you need to set multiple mailbox locations or want to change default | ||
| + | # namespace settings, you can do it by defining namespace sections. | ||
| + | # NOTE: Namespaces currently work ONLY with IMAP! POP3 and LDA currently ignore | ||
| + | # namespaces completely, they use only the mail_location setting. | ||
| + | # | ||
| + | # 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. | ||

| + | # 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/". | ||

History
- 2011-06-08 I think the only change to this file was to change auth default { socket listen { client { path= from "/var/spool/postfix/private/auth" to "/var/spool/postfix/private/dovecot-auth". Finally receiving Gmails, and no known errors. I also made these changes in User:Woozle/files/dovecot/auth.d/01-dovecot-postfix.auth, but it wasn't until I made them here that things started working.
Content
# leave this line or Group-Office will overwrite your config
## Dovecot configuration file
# If you're in a hurry, see http://wiki.dovecot.org/QuickConfiguration
# "dovecot -n" command gives a clean output of the changed settings. Use it
# instead of copy&pasting this file when posting to the Dovecot mailing list.
# '#' character and everything after it is treated as comments. Extra spaces
# and tabs are ignored. If you want to use either of these explicitly, put the
# value inside quotes, eg.: key = "# char and trailing whitespace "
# Default values are shown for each setting, it's not required to uncomment
# any of the lines. Exception to this are paths, they're just examples with
# the real defaults being based on configure options. The paths listed here
# are for configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
# --with-ssldir=/etc/ssl
# Base directory where to store runtime data.
#base_dir = /var/run/dovecot/
# Protocols we want to be serving: imap imaps pop3 pop3s
# If you only want to use dovecot-auth, you can set this to "none".
#protocols = imap imaps
protocols = imap pop3 imaps
# IP or host address where to listen in for connections. It's not currently
# possible to specify multiple addresses. "*" listens in all IPv4 interfaces.
# "[::]" listens in all IPv6 interfaces, but may also listen in all IPv4
# interfaces depending on the operating system.
#
# If you want to specify ports for each service, you will need to configure
# these settings inside the protocol imap/pop3 { ... } section, so you can
# specify different ports for IMAP/POP3. For example:
# protocol imap {
# listen = *:10143
# ssl_listen = *:10943
# ..
# }
# protocol pop3 {
# listen = *:10100
# ..
# }
listen = *
# Disable LOGIN command and all other plaintext authentications unless
# SSL/TLS is used (LOGINDISABLED capability). Note that if the remote IP
# matches the local IP (ie. you're connecting from the same computer), the
# connection is considered secure and plaintext authentication is allowed.
#disable_plaintext_auth = yes
# Should all IMAP and POP3 processes be killed when Dovecot master process
# shuts down. Setting this to "no" means that Dovecot can be upgraded without
# forcing existing client connections to close (although that could also be
# a problem if the upgrade is eg. because of a security fix). This however
# means that after master process has died, the client processes can't write
# to log files anymore.

# Log file to use for error messages, instead of sending them to syslog.
# /dev/stderr can be used to log into stderr.

# Prefix for each line written to log file. % codes are in strftime(3)
# format.

# Syslog facility to use if you're logging to syslog. Usually if you don't
# want to use "mail", you'll use local0..local7. Also other standard
# facilities are supported.
#syslog_facility = mail

## SSL settings
##
# IP or host address where to listen in for SSL connections. Defaults
# to above if not specified.
#ssl_listen =
# Disable SSL/TLS support.

## 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
# kept. 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/wiki/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
#
# <doc/wiki/MailLocation.txt>
#

# If you need to set multiple mailbox locations or want to change default
# namespace settings, you can do it by defining namespace sections.
# NOTE: Namespaces currently work ONLY with IMAP! POP3 and LDA currently ignore
# namespaces completely, they use only the mail_location setting.
#
# 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.

# Note that the client sockets must exist in the login_dir.

## 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.
# Extremely SLOW with Maildir. It'll eat your CPU and disk I/O.
# 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) when the user logs in.
# The existing mail directory is renamed to <dir>-converted.
#convert_mail = mbox:%h/mail
# Skip mailboxes which we can't open successfully instead of aborting.
#convert_skip_broken_mailboxes = no
# 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
# Lazy expunge plugin. Currently works only with maildirs. When a user
# expunges mails, the mails are moved to a mailbox in another namespace
# (1st). When a mailbox is deleted, the mailbox is moved to another namespace
# (2nd) as well. Also if the deleted mailbox had any expunged messages,
# they're moved to a 3rd namespace. The mails won't be counted in quota,
# and they're not deleted automatically (use a cronjob or something).
#lazy_expunge = .EXPUNGED/ .DELETED/ .DELETED/.EXPUNGED/
