Description: Secure open source IMAP and POP3 server
DescDetail: <<
Dovecot is an open source IMAP and POP3 server for Linux/UNIX-like
systems, written with security primarily in mind. Dovecot can work
with standard mbox and Maildir formats and it's fully compatible
with UW-IMAP and Courier IMAP servers' implementation of them, as
well as mail clients accessing the mailboxes directly.
<<
DescUsage: <<
Dovecot can use PAM (Plugable Authentication Modules) to authenticate
IMAP and POP user accounts. To allow dovecot to use PAM (RECOMMENDED),
copy %p/etc/pam.d/dovecot (or whereever you instaled Fink) to
/etc/pam.d/dovecot using the command:
sudo cp %p/etc/pam.d/dovecot /etc/pam.d
To use SSL connections for IMAP and POP connections (RECOMMENDED), you will
need to generate an SSL certificate. To generate the certificate:
sudo cp %p/share/doc/dovecot/dovecot-openssl.cnf %p/etc
edit %p/etc/dovecot-openssl.cnf to suit your organization
sudo sh %p/share/doc/dovecot/mkcert.sh
edit %p/etc/dovecot.conf to uncomment the ssl_cert_file and ssl_key_file
lines.
The dovecot server has been installed to start when you boot the machine.
To disable the server, run 'daemonic disable dovecot' as root. This will
not kill a running dovecot server, but will prevent the server from
automatically starting when you boot the machine.
Ensure that you configure dovecot for you system by editing
%p/etc/dovecot.conf as appropriate. You can then start up the dovecot
server using 'sudo daemonic enable dovecot' or by rebooting your machine.

+## 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 doc/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

+
+# 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.
