    Hi folks -

    I just discovered email filtering, and am having a fun time directing spam to my junk folder.

    On the User Level Filtering page (User Level Filtering), the Best Practices section recommends:
    .. using multiple, simple filters instead of a single, monolithic filter. Exim, your server's mail
    transfer agent, handles many small rules much more efficiently ... ​
    What's a reasonable number of conditions? For example, there are a whole slew of obvious
    marketing terms that, if contained in the Sender field, almost certainly signify a junk message.
    Are 5 conditions in a single rule reasonable?
    (e.g. Sender contains <obviousMarketingTerm1> or <obviousMarketingTerm2> ... or <obviousMarketingTerm5>)
    10? 20? Alternately, how many is too many?

    Also, presumably when I create a filter, there's a config file that's created somewhere.
    Can that be edited directly? Might that be more efficient than using the UI?

    Any & all insight welcome.

    Thanks kindly,

    - Richard

    Hello :)

    Using five conditions in a single rule should be fine. However, it's better to setup a filter, and then test it to see the results.

    Here is a post on where the user level filters are stored if you want to edit them manually:

    Thank you.
