Postfix and Procmail

First install Postfix

Spamassassin

Then install Spamassassin

Dovecot

Dovecot

after installation

Logging:

log_path = /var/log/mail/dovecot.err
info_log_path = /var/log/mail/dovecot.info

touch /var/log/mail/dovecot.err
touch /var/log/mail/dovecot.info

in /etc/logrotate.d/rsyslog add

/var/log/mail/dovecot.err
/var/log/mail/dovecot.info

to the rest of the mail lines

Create a maildir for www-data manually (dovecot has no permissions to create in /var/www)

mkdir /var/www/Maildir
chown www-data /var/www/Maildir

To test:

mutt -f imap://username@localhost
mutt -f pop://username@localhost

or to open a user's maildir:
mutt -m maildir -f ~user/Maildir

Roundcube webmail

We're going to get the backport version as it's much much better

so in /etc/apt/sources.list add

deb http://backports.debian.org/debian-backports squeeze-backports main

and to install

apt-get -t squeeze-backports install roundcube roundcube-mysql roundcube-plugins roundcube-plugins-extra

You will need mysql-server, apache2 and php5 as well.

then in /etc/roundcube/apache.conf

uncomment:
    Alias /roundcube/program/js/tiny_mce/ /usr/share/tinymce/www/
    Alias /roundcube /var/lib/roundcube

in /etc/roundcube/main.inc.php change

$rcmail_config['htmleditor'] = 0; to 1
$rcmail_config['preview_pane'] = 0; to 1
$rcmail_config['default_host'] = '127.0.0.1';
$rcmail_config['language'] = 'nl_NL';

Settings that need looking at and haven't been enabled yet!

$rcmail_config['smtp_server'] = 'localhost';
$rcmail_config['smtp_user'] = '%u';
$rcmail_config['smtp_pass'] = '%p';

in /usr/local/etc/php.ini

upload_max_filesize = 5M

Plugins

virtuser_file

This comes with the roundcube-plugins package and makes roundcube read the identities (@domain.ext) from a file in the format:

email@domain.ext user email2@domain2.ext user2

If a user has multiple @domain.ext set in the file, then it makes multiple entries you can choose from as your from address.

Find in /etc/roundcube/main.inc.php

$rcmail_config['plugins'] = array('virtuser_file');

To enable it. and then all the way at the bottom set

$rcmail_config['virtuser_file'] = '/etc/postfix/virtual';

DragnDrop Attachments

You can find that here

download, then unzip and mv to /var/lib/roundcube/plugins/dragndrop_attachments/

In main.inc.php

$rcmail_config['plugins'] = array('virtuser_file','vcard_attachments','show_additional_headers','emoticons','jqueryui','dragndrop_attachments', 'vacation');

Vacation autoresponder

Download it from here

unzip it to /var/lib/roundcube/plugins/vacation/

The config.ini should look like this:

[default]
driver = "ftp"
subject = "Afwezig"
body = "default.txt"

[dotforward]
binary = "/usr/bin/vacation"
flags = ""
message = ".vacation.msg"
database = ".vacation.db"
alias_identities = true
set_envelop_sender = false
always_keep_message = true

in Roundcube 0.5 the page layout has changed and the plugin displays incorrectly. To fix this, edit

plugins/vacation/skins/default/vacation.css

and add in some padding:

#pagecontent {
width: 800px;
padding-top:70px;
}

Also edit plugins/vacation/default.txt

Note that it won't save the autoresponder message and subject if you don't tick the checkbox on the top of the page (which we've moved down a bit above)

Finally, add 'vacation' to the $rcmail_config['plugins'] in roundcube main.inc.php

You can find the auto reply in the settings

NB. when testing, you may need to delete the users from the database to check if certain settings are being set before logging in.

Converting from mbox to maildir

Because we want the system to support IMAP functionality fully, there are some changes to to be made which will be documented further. For now, look at Converting from mbox to maildir
