Summary: Ability to add whitelisted addresses

Initial Comment:
DSPAM can be a bit slow to learn emails you only get say once every few months 
it would be great if you could manually add a whitelisted address in the DSPAM 
UI.

While this can be done at the MTA level that would mean bypassing DSPAM and 
missing an opportunity to train the database.

Message:
The problem with the addressbook lookup is that not everyone has the
possibility to query the addressbook for each and every user. Some mail
clients have their addressbook locally and querying the addressbook is not
possible.

I think we NEED to educate the DSPAM user base that whitelisting manually
in DSPAM is a bad thing. I mean: If whitelisting in DSPAM is the most
significant thing keeping mail from a certain sender to not get tagged by
DSPAM as spam, then you have definitely a big problem. Then your
data/tokens in DSPAM are in a very, very bad shape and it's good, that
DSPAM tagged the message as SPAM (forcing you to reclassify and help DSPAM
learn).

I do however have some things in my mind that could help accelerating
whitelisting in DSPAM. One thing would be to add a special whitelist token
for the senders domain and use that to slightly tune the probability
towards innocent if there is a positive match or a higher hit in innocent
then in spam. Another thing could be to parse all the received header lines
and construct some kind of "trusted delivery path" in relation to a sender
and/or sender domain. And have that "trusted delivery path" behave +/- the
same as mentioned above. Or forget all that token thing and introduce a
plain text file or preference where one can just add the bare email address
and use that to whitelist BUT in case of whitelisting that way NOT
automatically train DSPAM with the tokens (that would come +/- to the same
technique as doing it on the MTA level).

But again: I am not that hot in adding users manually to the DSPAM
whitelist. I know, I know... people like it but as I wrote above: If
whitelisting is the thing keeping your DSPAM instance in not tagging a big
part of your mail communication as spam, then your tokens are in a very bad
shape.

In itself, this looks like good idea and it has come up as a feature
request many times on the dspam-users list.

However, using the "bare address" can be easily abused by spammers
masquerading as someone you know (which, I believe, is quite common right
now). This would completely defeat the purpose of dspam. We need to
rethink
this one if we want to implement it.

How about looking through your address book to whitelist everything in
there automatically? Steeve, what do you think, could your patch achieve
this? But we still need to figure out how to do it without making a
convenient security hole for spammers. I have some far-fetched ideas, but
they all seem to need the cooperation of the sender.

Ideas?

Hallo Paul

This would be possible to do. But one issue is that DSPAM does use the
whole FROM line for the white list and white listing your buddies from
day
one would require you to know the exact FROM line of their mails. Another
option would be to weaken the white listing algorithm to just include the
bare email address and white list just the pure bare email address.

I could write easy a patch for that. Let me know if you need/want that.

Kind Regards from Switzerland

Steve

WHITELIST IMPROVEMENT IDEAS

Option via web gui to set whitelist from day one.

Instead of waiting for 10+ email to pass for auto white listing, it would
be good to setup your known buddies from day 1 of using dspam-community
