Hi,

 

It really boils down how you have implemented dspam with postfix.

You can create two transports, one for learning and one for inoculation.

Next all mails to heavily spammed e-mail address goes directly to inoculate.

Why should you first go to learn and then go to inoculate if your assumption is 
that the mail is spam anyways?

 

Regards,

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
