Keeping spam and ham from previous mail server

[johan.radyn]

I need to migrate to a new mail server and two of my friends both suggested Zimbra on separate occasions. I'm migrating from an old and very unstable Kolab installation and I have already moved all the users and their mails to my new Zimbra installation, but just to push the envelope a bit further I was wondering if I could keep/move/retrain the currently trained spam and ham to the new server?

Thanx for the help.

Welcome to the forums

Do you still have the emails or just the bayes database ?

Thanx for the welcome..

I have the last month's worth of email and the bayes database, thus in essence just the database to work with.

If all you have is one month of data, I'd suggest you don't bother as Zimbra will automatically train it's own spam filters.

Okay, not tried but here we go On your old server you will need to dump the bayes database with

sa-learn --backup > bayes.txt

transfer this file to your ZCS server into /tmp. Then this will need to be imported

su - zimbra
/usr/bin/sa-learn --dbpath=/opt/zimbra/data/amavisd/.spamassassin -C /opt/zimbra/conf/spamassassin --restore /tmp/bayes.txt

Just to be clear then.. Definate not worth transfering the month of data that I have, and I can't transfer the bayes database with 3 years worth of data..?

Thanx

Please update your profile with the output from

su - zimbra
zmcontrol -v

as dependant on which version you are using the SA bayes path could be different.
