    Default Spam Threshold

    I was looking, I see where spam is trashed at 75% and placed in Junk at 33%.
    I was wondering if there is a way to change these settings.
    I would like to lower the junk folder setting to say 15% I am still seeing too many spam messages in the inbox. I am using Zimbra 4.0.3

    Regards.

    You make the changes in the admin UI, don't lower that to a very low number. I'd try lowering them a little at a time to make sure you don't get any false positives. There are also other things you can try to catch more spam, do a search of the forum and wiki for alternatives.

    Default Was not checked enabled

    I have been seeing the headers marked showing the DSPAM results.
    I assumed the spam was being being trained so I had not really worried about it until now
    I must have overlooked this setting, or assumed it was enabled by default because the header information but, either way I see it was not even checked enabled.
    So does this mean that all the mail that was placed in the junk folder over the last month (when I switched over to zimbra) was not being trained?

    Default

    It should be getting trained by the zmtrainsa cron job which runs nightly, that checks the spam account. You can see if DSAPM has anything by doing: /opt/zimbra/dspam/bin/dspam_stats -H - that should give you some statistics for DSPAM.
