Over the years I've ended up with some email addresses that are heavily spammed and no longer in use.

I'd like to take advantage of them as a honeypot for inoculation, with the knowledge that they only receive spam.

I run Postfix and use dspam as a post-queue filter, as described at http://www.postfix.org/FILTER_README.html#advanced_filter

As a result, all mail gets classified/before /I know the final recipient, as local aliases haven't been evaluated yet.

I'd like to "deliver" mail for these destinations by routing all of it through something like

        | dspam --client --user <user> --source=error --class=spam

without having to first determine if it was improperly classified as non-spam.

Reading DSPAM(1) reveals

    You should use error only when DSPAM has made an error in clas-
    sifying  the message, and should present the modified version of
    the message with the DSPAM signature when doing so.

Does this mean that if the message was originally classified as spam that the token and message counts
are "blindly" incremented each time it is called,
or does dspam check to see the classification of the message ID before incrementing the counts?

As easy as it would be to grep for 'X-DSPAM-Result: Innocent', it starts getting messy since I also either need the full message or the signature (another grep pass) to pass to dspam.


If I can't just feed the message into the reclassify dspam call, are there any "elegant" approaches to this?


Thanks!


Jeff
