I want to rsync on my local-host via ssh from a remote host without a ssh enabled root account but full access to the whole filesystem.

local-host:

ssh-keygen -t rsa

copy ~/.ssh/id_dsa.pub to remote-host:/home/rsyncuser/.ssh/authorized_keys

rsync files with ssh:

rsync -vaHxr --numeric-ids --delete --rsync-path=rsync_wrapper.sh \
      -e "ssh -c arcfour -o Compression=no -x" \
      rsyncuser@remote-host:REMOTEDIR LOCALDIR

remote-host (source of files to rsync):

groupadd -g 3001 rsyncuser
useradd -u 3001 -g rsyncuser -s /bin/bash -m rsyncuser

/home/rsyncuser/.ssh/authorized_keys:

from="192.168.0.2,",command="/home/rsyncuser/validate-rsync.sh"
 ssh-dss 012345678...

limit access with from (optional).
On sucessfully ssh login command is executed.

/home/rsyncuser/validate-rsync.sh:

#!/bin/sh
case "$SSH_ORIGINAL_COMMAND" in
    *\&*)
        echo “Rejected”
        ;;
    *\;*)
        echo “Rejected”
        ;;
    *\(*)
        echo “Rejected”
        ;;
    *\{*)
        echo “Rejected”
        ;;
    *\<*)
        echo “Rejected”
        ;;
    *\`*)
        echo “Rejected”
        ;;
    rsync\ --server*)
        $SSH_ORIGINAL_COMMAND
        ;;
    *)
        echo "Rejected"
        ;;
esac

/usr/bin/rsync_wrapper.sh:

#!/bin/sh
/usr/bin/sudo /usr/bin/rsync "$@";

/etc/sudoers:

rsyncuser ALL = NOPASSWD: /usr/bin/rsync

apt-get install spamassassin spamc re2c make gcc libc6-dev

I want to run spamassassin as non root user.

groupadd -g 3000 spamd
useradd -u 3000 -g spamd -s /bin/false -d /var/lib/spamassassin spamd
mkdir /var/lib/spamassassin
chown spamd:spamd /var/lib/spamassassin

/etc/default/spamassassin:

ENABLED=1
OPTIONS="--create-prefs --max-children=5 --ipv4-only --username spamd \
         --helper-home-dir /var/lib/spamassassin -s /var/log/spamd.log"
PIDFILE="/var/run/spamd.pid"
CRON=1

/etc/logrotate.d/spamassassin:

/var/log/spamd.log {
        rotate 5
        daily
        compress
        copytruncate
        missingok
}

/etc/spamassassin/local.cf:

report_safe 0
lock_method flock
required_score 5.0
use_bayes 1
bayes_auto_learn 1
bayes_ignore_header X-Bogosity
bayes_ignore_header X-Spam-Flag
bayes_ignore_header X-Spam-Status

in /etc/spamassassin/v310.pre disabled Pyzor, Razor2 and SpamCop
in /etc/spamassassin/v320.pre enabled loadplugin Mail::SpamAssassin::Plugin::Rule2XSBody

/etc/postfix/master.cf:

cyrus unix - n n - - pipe flags=R user=cyrus argv=/usr/bin/spamc -f -u spamd \
   -e /usr/sbin/cyrdeliver -f ${sender} -m ${extension} ${user}

i want to use a compiled ruleset for spamassassin
#> sa-update
#> su spamd -s /bin/sh -c sa-compile
#> invoke-rc.d spamassassin reload

users should be able to tell the mailserver what mails a spam or ham.
i created public mailboxes where uses can move sam or ham mails into:

sudo cyradm --user cyrus --server localhost
cm user.spam
sam user.spam anyone p
sam user.spam admin all
cm user.nospam
sam user.nospam anyone p
sam user.nospam admin all

Two cronjobs monitors these folders and let spamassassin learn.
/etc/cron.d/spam-learn:

*/5 * * * * root for n in /var/spool/cyrus/mail/s/user/spam/*\.; \
do [ -f "$n" ] && /usr/bin/sa-learn --dbpath /var/lib/spamassassin/.spamassassin \
--spam $n && rm -f $n && su cyrus -c "/usr/sbin/cyrreconstruct user.spam"; done

/etc/cron.d/nospam-learn:

*/5 * * * * root for n in /var/spool/cyrus/mail/n/user/nospam/*\.; \
do [ -f "$n" ] && /usr/bin/sa-learn --dbpath /var/lib/spamassassin/.spamassassin \
--ham $n && rm -f $n && su cyrus -c "/usr/sbin/cyrreconstruct user.nospam"; done

Spamassassin marks mail-headers with X-Spam-Status. According to this users can create an own spam folder and with a sieve filter automatically move them to this folder if X-Spam-Status is Yes.

Because we are running as spamd

/etc/cron.daily/spamassassin

-sa-compile > /dev/null 2>&1
+su spamd -s /bin/sh -c sa-compile > /dev/null 2>&1
