Bayesian Analysis Feeder mailet
This was asked before but I didn't see a response. Is it possible to send a
message with multiple spam/ham attachments to the spam/ham feeder or is it
strictly one attachment per message? [james 2.3]
Also, It seems like spammers could easily feed their email to the ham feeder
if steps aren't taken to prevent them from doing so. Is there a simple way
to prevent people from feeding spam/ham by requiring them to be smtp
authorized or something like that? Thanks. -- Bud

Yes. But in addition to that you would need to manually update the
bayesiananalysis_messagecounts table counters: as the process is to
automatically add 1 to the ham or spam counter, if you feed say 10
attachments you should manually add 9 to the counter.
If the current value of the counters are already high, a small
percentage of "error" in the counters can be ignored (say if you have
already 1000, ending up with 1001 instead of 1010 doen't matter).

Your concern is perfectly correct. To avoid this I have SMTP AUTH
activated and use a config line like the following:
<mailet match="RecipientIs=spam@internal.use"
class="BayesianAnalysisFeeder">
where "internal.use" is any not-existing domain (or anyway a domain
different from my servernames). The same applies to ham.
This way only SMTP AUTHenticated users will be able to feed spam/ham
messages.
Another way is to add a match="SMTPAuthSuccessful" somewhere in the
config.xml logic, but the previous solution IMHO is simpler.
Ciao,
Vincenzo

No, multiple attachments are not supported. If you, as an administrator,
need to make a one-shot large feed you can exploit the trick I told you.
But it is *not* for users.

*Much much worse*, a user by mistake can feed ham as spam or vice-versa.
The only way is to limit the feeding capability to few reliable users.
It is part of the game. Having instead personal lists would be not
effective.

I have to look at it....

Am I reading this correctly? "manually update..."??? You say it's
possible to send multiple attachments to the feeder. But everytime I or
any one of my hundreds of users choose to do so, I somehow have to know
a) that it occurred, and b) know precisely how many attachments were
sent in, and then go manually update a field in a database table to
reflect that number? I'm obviously missing something. If this is
indeed the case, the answer is, "no... multiple attachments are not
supported".
What's going to happen if I don't keep up with it? There's no way I can
monitor and manually update this with as many users as I have. How
would I know to begin with that someone had sent multiple attachments?
There is no way I'm going to be able to prevent them from sending
multiple attachments. I understand you said small descrepancies in the
numbers are ok. This is quickly going to become NOT small descrepancies.
Just out of curiosity... why can't the feeder simply update the counter
itself on multiple attachments? It does it on single attachments,
doesn't it?
