    Default Spam issues with 3.1.0

    I've noticed after upgrading from 3.0.1 to 3.1.0 RHEL4_GA version that I'm getting a lot more Spam in user inboxes that aren't being filtered into the Junk box.

    I've checked what I can think of in the Admin Console, and SpamAssassin is enabled, and I have restarted Zimbra. What can I check to make sure everything is working fine?

    Thanks,

    Andy

    What are the tag and kill levels set to? I have mine set to 25/66 respectively and see almost no spam. Are the overnight zmtrainsa cron jobs being run?

    Bill,

    I had the default levels of 33/75, but I've now changed them to your recommendation I don't see any errors about failed cron jobs. I'll give it a few days to see if it catches the junk now.

    Thanks

    Also take a look at the spam that is making it into the inbox. Post some headers here and we'll take a look.

    I usually find those levels OK without being too agressive. You could also have a look at setting 'rules_du_jour' for adding some more filtering with spamassassin, see the links in this thread. There are lots more tests you can apply to Spamassassin but the trick (if you can call it that) is for it not to get rid of legitimate email. If you do use the rules_du_joru or add any of your own rules then relax the tag and kill percentages again and monitor what sort of email is getting tagged as spam, if there are no false positives you can change the tag/kill levels as you need.

    Thanks for the advice on the levels. Looks like everything is working as it should be.

    Most appreciated,

    Hi Andy

    Glad that's OK. It's damned good this Zimbra stuff, isn't it?
