    Question Server Wide Filters

    I have recently migrated to Zimbra from an IMail system. One of the features that I am sorely missing is the ability to define Global/Server Wide Filters.

    For example...

    1) Forward a copy of any email sent by user@test.com to this list@company.com (regardless of the recipient of the email)

    2) If the to address is in the format xxxx-list@test.com and subject contains Out of Office then delete it.

    All the Zimbra mail filters seem to be account specific and the first rule example is not possible without defining a rule under every account. Furthermore setting the rule on every account won't work if the recipient of the original email is on the distribution list specified creating an infinite mail hop loop. (e.g. user@test.com -> bob@company.com -> list@company.com -> bob@company.com -> etc etc...)

    I realize that the second rule could likely be accomplished by creating a custom SpamAssassin rule - although that seems hackish especially when factoring in whitelisting.

    This seems like this may be something that is needed at the postfix level - kind of at the same level as the alias/distribution list mapping side. Either that or maybe there is something that can be done with the amavisd-new.

    Does anyone know of filtering tools that work with Zimbra, Postfix, or amavisd-new that are specifically designed to do rules processing and manipuation on inbound email traffic before it gets to the user's mailboxes?

    Thank you

    Default Another Example

    One more example....

    3) Auto respond with a "your message has been received" email to any email that arrives on xxxx-list@test.com. (This cannot be done at the user level because the email goes to multiple users).

    To answer your first point, you may find this useful: [SOLVED] Law Enforcement (aka intercept)?

    The law enforcement filter won't really work for the desired behavior, because once again this is tied to a local user account. In the example 1 the user@test.com is an "external" user account.

    As a more concrete example - if we have high priority clients we would want to put a rule in that says - any email originating from these clients will get forwarded to a senior client manager regardless of the destination email address that the client entered.

    So we are not looking to track all traffic from one of our internal users - we are looking to be able to put filtering rules for all Inbound messages that come to our server regardless of the destination.
