SquidGuard is a URL redirector used to use blacklists with the proxysoftware Squid. There are two big advantages to squidguard: it is fast and it is free.

Various bits of code, scripts, and procedures were put together with information from John Simpson's qmail.jms1.net website. It's an excellent resource on managing and setting up a Qmail server.
The Dovecot IMAP server has Sieve support via a plugin provided by the Pigeonhole Project
Installation
Download the latest source from the Pigeonhole download page:
cd /extra/src
wget http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.9.tar.gz
tar zxf dovecot-2.2-pigeonhole-0.4.9.tar.gz
cd dovecot-2.2-pigeonhole-0.4.9Since we installed Dovecot from source, the configure script should find the installed dovecot-config automatically:
./configure
make
make installIMPORTANT: You need to recompile Pigeonhole when you upgrade Dovecot to a new version, because otherwise the Sieve interpreter plugin will fail to load with a version error.
A set of sample config files are installed to/usr/local/share/doc/dovecot/example-config/conf.d, which you'll have to move to /usr/local/etc/dovecot/conf.d:
cp /usr/local/share/doc/dovecot/example-config/conf.d/20-managesieve.conf /usr/local/etc/dovecot/conf.d/
cp /usr/local/share/doc/dovecot/example-config/conf.d/90-sieve.conf /usr/local/etc/dovecot/conf.d/Edit /usr/local/etc/dovecot/conf.d/20-managesieve.conf and uncomment a couple lines:
protocols = $protocols sieve
service managesieve-login {
inet_listener sieve {
port = 4190
}
service_count = 1
vsz_limit = 64M
}
Enable the proper extension address delimiter in /usr/local/etc/dovecot/conf.d/90-sieve.conf:
recipient_delimiter = -Enable the Sieve plugin for Dovecot's LDA in /usr/local/etc/dovecot/conf.d/15-lda.conf:
protocol lda {
# Space separated list of plugins to load (default is global mail_plugins).
mail_plugins = $mail_plugins sieve
}Skipped these steps and seems to work fine...
Edit /usr/local/etc/dovecot/conf.d/10-master.conf and give the vpopmail user and group some access privileges:
default_login_user = vpopmail
default_internal_user = vpopmail
service auth {
# auth_socket_path points to this userdb socket by default. It''s typically
# used by dovecot-lda, doveadm, possibly imap process, etc. Its default
# permissions make it readable only by root, but you may need to relax these
# permissions. Users that have access to this socket are able to get a list
# of all usernames and get results of everyone''s userdb lookups.
unix_listener auth-userdb {
mode = 0600
user = vpopmail
group = vchkpw
}
# Postfix smtp-auth
#unix_listener /var/spool/postfix/private/auth {
# mode = 0666
#}
# Auth process is run as this user.
user = $default_internal_user
}
service auth-worker {
# Auth worker process is run as root by default, so that it can access
# /etc/shadow. If this isn''t necessary, the user should be changed to
# $default_internal_user.
user = $default_internal_user
}
Restart Dovecot:
svc -t /service/dovecot-imapTo enable Sieve filtering for a:
- single-user - you can edit/create that user's
.qmailfile to use Dovecot's LDA:
| DTLINE=${DTLINE/$USER-} /var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d ${EXT/-*}@$USER -a $EXT@$USER
# This one does not work with user-ext@domain addresses
#|/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -d $EXT@$USER - domain - must edit that domain's
.qmail-defaultfile to use Dovecot's LDA instead ofvdelivermail:
| DTLINE=${DTLINE/$USER-} /var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d ${EXT/-*}@$USER -a $EXT@$USER
FIXED NOTE! Interferes with extension (-ext) addresses.
NOTE! Using Dovecot's LDA conflicts with using Qmailadmin to create vacation autoresponders!!!
NOTE! The change to .qmail-default conflicts with mkauth script - line 398 - where it checks for vdelivermail.
