    Default Spam Tag / Kill Options

    Hello, we are looking at Zimbra as a replacement for some of our customers.
    We usally supply Ensim servers which use SpamAs and MailScanner.

    In our tests so far, we've found that the Zimbra is not Tagging Spam as we would expect. We've tried putting the Kill % to 0 and Tag to 10 %

    Would this Kill all spam, as it's 0% and Higher or would a Kill % of 0 disable this option? What we are trying to do is monitor how much individual spams are tagged.

    In future it'd be great to have spam settings for each user, not a system wide setting.

    We are now testing with kill % at 100 and tag at 20%. I think from the documentation that this configuration will tag messages the server is 20% sure is spam and kill anything that is 100% deff spam. Correct?

    Any more detailed explination of this Percentage Option would be appreciated.

    Thanks for a great Open Source tool !

    One other thing we've noticed is that the Anti Spam and Anti Virus tabs, in the admin control panel are only in the Global Settings options, should they be present in the server options as well?

    The Class Of Service has both options enabled.

    Default spam tagging

    The spam tag and kill percents determine what is tagged and passed on or dropped by the MTA.

    The percentages correspond, in SA, to a score range of 0-20 so a spam kill level of %100 will kill anything which scores higher than 20 (not much spam).

    The defaults, which are (IIRC) tag:30 kill:75 correspond to scores of 6 and 15 for tag and kill, respectively.

    SO - to tag and kill MORE spam, lower the percentages. To pass more spam, raise the percentages.

    The scores are in the global sections only, since in a multi-mta environment, it doesn't seem desirable to have some MTAs pass more spam than others.
