    Question How to: white list all contacts

    Before using zimbra I use to have the Anti-Spam-SMTP-Proxy (ASSP) (http://assp.sourceforge.net) which was just before the smtp filtering spam.

    The question I have is how would we white list automatically all our contacts in order to bypass all filters.
    The principle is that if I am sending an email to somebody is because I trust him, so even if his IP is blacklisted I should be able to get his emails.

    Is this possible in zimbra?

    Cheers,

    sturgis

    You can't automatically whitelist your contacts. Check the wiki for 'whitelisting', there may be an RFE in bugzilla for this. If there is, vote and if not file & vote.

    It could be handeled if zimbra also added a new layer of protection via ASSP (Anti-Spam SMTP Proxy Server) or similar

    http://assp.sourceforge.net/

    It provides (extracted from the web):

    1. Easy browser-based setup (optional).
    2. Uses your existing message transport and existing SMTP server.
    3. Works with Sendmail, qmail, Postfix, Imail, Exchange, Courier, Mercury, Lotus Notes, and all other standard SMTP servers.
    4. Runs on Linux, Unix, Windows, OS X, OS/2, and more.
    5. Automatically customizes to your site's unique email profile.
    6. Automatic whitelist -- noone you email will ever be blocked.
    7. Early Sender validation -- Kills most spam before it ever reaches the server.
    8. Senders receive immediate notification if mail is blocked but no erroneous bounces are ever generated.
    9. Redlist keeps an address off the whitelist.
    10. No-processing addresses pass through.
    11. Makes use of honeypot type spambucket addresses to automatically recognize spam and update your spam database.
    12. Bayesian filter intelligently classifies email into spam and non-spam.
    13. Supports additional site-defined regular expressions to identify spam or non-spam email.
    14. Can optionally block all non-whitelisted email (for anti-spam zelots).
    15. Mime encoded and other camouflaged spam is also recognized.
    16. Automatically maintains the spam and non-spam databases.
    17. Accepts whitelist submissions and spam error reports by authorized email.
    18. Optionally rejects executable attachments from non-whitelisted (or all) addresses.
    19. Free (as in speech) software -- Licensed under the GPL.
    20. Practically no maintenance required.
    21. Active user community and email list for support questions.
    22. Source code included if you need to customize your installation.
    23. Runs as a service in Windows NT / 2000.
    24. Optionally blocks no mail but adds an email header and/or updates the message subject.
    25. Optionally uses community-based spam statistics to identify hosts that are likely to send spam or non-spam mail.
    26. In *nix environments can switch to non-root user. Also supports chroot jail.
    27. Individual users can be configured to receive all mail.
    28. Shows detailed analysis of spam rating process for specific messages.
    29. Option to forward a copy of every rejected mail to an address.
    30. Can block spam-bombs (when spammers forge your domain in the from field).
    31. Keeps spam statistics for your site.
    32. Detailed documentation.
    33. Can listen on more than one smtp port.

    Have you, or anyone else, implemented it with Zimbra? Have you entered it in bguzilla as an RFE?

    Yes I did enter it in bugzilla.
    I am new in zimbra. I first installed it in mod_jk but I had a lot of problems.
    Now I just run it in a different port than my apache server.

    Before I used ASSP and I was very happy with it. Unfortunately I have no clue on how to integrate it with zimbra.
    You could just install it, as it is a proxy server, but ASSP to learn from what is spam and what it is not, you have to forward the spam to an email address. That would the the customization at zimbra side...
