Scalix is now a mature email server, reliable and powerful, that can accommodate environments with thousands of users.
Most of the tasks can be accomplished using the web interface, which is a nice and intuitive interface. However, not all the tasks needed for a day to day administration are available from the web interface.
Here are some command line Scalix administration commands for the daily use as an email administrator.
Check Scalix services from CLI
lsof –i:25 lsof –I:143 lsof -i :5733 ps -ef | grep postmaster
Users unable to VIEW the inbox content
Try the following steps.
omshowu -n username -f
This should give you the location of the user folder similar to this "~/user/g000038".
Go to /var/opt/scalix/ll/s/user/g000035 (in our case) and remove the "imap-cache" directory then restart the imap server (users will get logged off).
rm -r imap-cache
STOP and START IMAP
Restart IMAP service: omoff -d 0 -a IMAP & omon IMAP
Users unable to VIEW some of the inbox content
Ask the user to log off!!! AND to stay logged off until you finish!!!!
View which users are loged on: omstat -u all
View the process associated with that user: ps -ef | grep 55003 Where 55003 is the user id.
Kill the processes associated with that user: kill -9 “process id”
Fix the mailbox: omscan -Avfx -U “User Name”
Restart the scalix service: omshut -t3 && sleep 3 && omrc
Delete the user’s 3d files in the above folder (/var/opt/scalix/ll/s/user/g000035)
Issues with the web interface
Restart Tomcat and Apache2 /etc/init.d/scalix-tomcat stop rcapache2 stop
rcapache2 start /etc/init.d/scalix-tomcat start
CDA server not starting
omoff -d 0 -w cda omreset -o off cda
delete the lockfile, (if it exists):
rm /var/opt/scalix/ll/s/sys/omcda.lock omon cda
Automated update via crontab
(this will update the filesd and restart spamassassin)
Update rules are located at:
Edit Spamassassin Whitelist and Blacklist
Entries should be of the form: whitelist_from email@example.com
vi /etc/mail/spamassassin/vi whitelist.cf
Entries should be of form: blacklist_from user@domainname
when whitelist and/or blacklist are modified…
- check for error: spamassassin –lint
- restart spamd /etc/init.d/spamd stop and then /etc/init.d/spamd start
Check bounces email on Postfix
tail -f /var/log/mail | grep NOQUEUE
Troubleshoot sending or receiving
- Check the ldapmapper and make sure it’s working.
- Check the sendmail daemon – make sure it’s working.
ps aux |grep sendmail
You should see two things: Accept connection and Queue control
If you don’t see them, restart the service. Sometimes you need to create your own script for starting sendmail, instead of using the one that comes with the distribution.
Clean Scalix Queues
Service router queue, Internet Mail Gateway queue, Local Delivery queue.
CLEAN INTERNET MAIL GATEWAY QUEUE
echo -e "A$(( $(date +%d) + 10 ))E\nl\nunix\n\n" | omqdump -p | ./clearq.pl | tee output
CLEAN LOCAL QUEUE
echo -e “A$(( $(date +%d) + 10 ))E\nl\nlocal\n\n” |
omqdump -p |
CLEAN ROUTER QUEUE
echo -e “A$(( $(date +%d) + 10 ))E\nl\nrouter\n\n” |
omqdump -p |
Always use a new file, output is a sample file name
Once done, de-activate scalix services , except omstmon, omsessd, queue.manager and RUN OMSCAN (this will synchronize the database)
stop scalix normally, start scalix normally.
