    Default Spamassassin Contacts Whitelist

    On my current qmail/vpopmail/Courier IMAP implementation I have a cron job that looks through the 'Sent Items' folder, extracts valid email addresses, and adds them to a system wide spamassassin whitelist.

    How would one implement such a thing with Zimbra? My initial guess would be a method for spamassassin or postfix to look at the GAL or the emailed contacts for the user (or for all users) but for the how part I need some direction.

    Thanks

    I have a zimlet/admin extension that will do exactly this. It's not working fully quite yet, not quite ready for public release, I plan on releasing it by the end of the month. (you may feel free to hound me if you need that functionality).

    Details:

    The Zimlet allows you to publish individual contacts into a whitelist ("add contact to whitelist, "remove contact from whitelist") and the admin zimlet allows the administrator to remove entries from the global whitelist. That communicates with a server that maintains the whitelist database.

    I'd be happy to do some testing for you, its not an emergency on my part but a definate must have at some point.

    I'm running zcs-4.0.3_GA_406.RHEL4 on Centos 4.4 inside Vmware.

    I'd be more than happy to help you test out the zimlet, I'm currently usign zimbra 4.5 and was looking for a zimlet to tryout in the new deployment section, not to mention that control of the whitelist is essential

    I would be very interested to see how you are doing this in a zimlet, as I have a few ideas based around this but do not know where to start in writing one.

    OK, now I'm hounding you.

    Is there anything I can do to help speed development of this zimlet?

    I think your better bet is gonna be this bug.
    http://bugzilla.zimbra.com/show_bug.cgi?id=6953

    It's something we're actively working on.

    In the meantime this is working for me:
    Code:
    #!/bin/bash
    ACC=`zmprov gaa`
    for i in $ACC
    do
    zmmailbox -z -m $i gact | grep -u email: | sort | uniq | sed -e 's/email:/whitelist_from/g' >> autowhitelistall.tmp
    done
    cat autowhitelistall.tmp | sort | uniq > autowhitelistall.cf
    rm -f autowhitelistall.tmp
    zmamavisdctl restart
    It's not domain specific but that works better for me anyway.
